Measure that dresser carefully, because if there is one more inch in it, and you can fit a 10 gallon, you should do so. The larger the tank, the easier for a beginner. A 5 gallon with a betta is fine, but if you are wanting to make sure you stick with it, making it easier to keep everything stable is important.
Look around at tanks, see what the biggest one you can find that will fit. Look at 6.5 gallons, etc. Here is one that I think looks like it might work well for you: https://www.amazon.com/AquaView-6-5-Gallon-Power-Filter-Lighting/dp/B0182CAHWS/ref=sr_1_5?crid=1OYW8NLJU5D4O&dchild=1&keywords=7.5+gallon+aquarium&qid=1600223281&sprefix=7.5+gallon+aqu%2Caps%2C177&sr=8-5
But there are likely better, that is just a quick search.
You stocking sounds good, and resist the urge to add to it, even if you get a bigger tank. A betta will be very happy alone in a tank that is 10 gallons or even larger!
Don't discount the possibility of a female betta. Female bettas are more active and faster swimmers, but are still beautiful fish. If you think you might want something for more movement, go female. You will also have less potential problem with a female nipping on its own tail.
There is another sub /r/bettafish that you might also want to sub to, as they are betta specific.
So far as plants, I would recommend something that floats, and one that attaches to something, and none that need to be directly planted. That makes aquarium care much easier. Marimo "moss" balls are also good (and easy) additions to the tank.
As others have said, be sure to cycle . . . but there are ways to cheat if you are impatient. You can buy pre-cycled media and be up in running pretty quickly.

But... What about fish? A plant is just going to sit there, and if you don't take care of it properly or if it's "wrong" for your conditions, it may take some time to die off and depress you.
I haven't messed with fish in decades, but a quick search reveals something like this at $40-ish: https://www.amazon.com/KollerCraft-Gallon-Aquarium-Internal-Lighting/dp/B0182CAHWS/ref=zg_bs_2975460011_20?_encoding=UTF8&psc=1&refRID=Z83D24P2P8GMZW5FS6GC
Fish would be a little more active than plants but still without commitments like you would have with a furry, cuddly pet that needs multiple feedings and cleanings throughout the day.
Umm.. ok. Unfortunately, if that bowl is Liam’s permanent home, he won’t have the really great life that he deserves. No living fish should be forced to live in such a tiny bowl/tank permanently.
A 5gallon is the recommended minimum tank size to give your new pal the best possible quality of life... You can keep him TEMPORARILY in the bowl but you’ll need to change the water DAILY with fresh dechlorinated water (or pure spring water works too but is a bit more costly) since such a small container is going to foul up fast. Remove any leftover food/waste ASAP as soon as you see it.
A larger tank is going to be more stable and better for the betta in the long run. I really hope you’ll upgrade him sooner rather than later.
Some cheap ones can be had:

https://www.petsmart.com/fish/starter-kits/top-fin-imagine-aquarium-kit-38988.html?cgid=300128 (be sure to get the 5gal. version currently priced at $25.99 at the time of this comment, DO NOT USE THE DIVIDER, I’m linking you this tank with the intent that you only put one betta in it, 5g for one single betta).
https://www.amazon.com/AquaView-6-5-Gallon-Power-Filter-Lighting/dp/B0182CAHWS
I recommend a sponge filter which isn’t included in those kits but would be gentler/more effective for a betta than those filters included in the tank kits. Also recommended a 25w heater (assuming you go for 5 g tank) with a manual temperature control knob since preset heaters are not accurate.
Once you have the 5g tank, sponge filter, and proper heater, you need to do Fish-in Nitrogen Cycle: https://www.reddit.com/r/bettafish/wiki/fishincycle
Must Have Items for your Nitrogen Cycling process + Additional Info:
https://www.amazon.com/Seachem-116012300-Stability-500ml/dp/B0002APIIW <-- Beneficial Bacteria blend, add 2x-3x the recommended amount of this directly into the filter, filter media, & tank water, especially after a water change. Add the bene-bacteria on a DAILY basis, for up to a week or longer if you like. Don't worry about "overdosing" on Bene-bacteria, the more the better when trying to kickstart a nitrogen cycle.
https://www.amazon.com/Seachem-116043304-Prime-500ml/dp/B00025694O/ <--Best water conditioner, also temporarily binds ammonia into less harmful form.

Three main things to check daily or every-other-day: Ammonia, Nitrite, and Nitrate. Not cycled will read 0 Ammonia, 0 Nitrite, 0 Nitrate. Cycling in progress will read some ammonia and/or some nitrite, but little or no nitrate. Fully Cycled will read 0 Ammonia, 0 Nitrite, and 5-10 ppm of Nitrate, then when nitrate reaches 15-20 ppm in a cycled tank a water change is necessary to reduce said nitrates.
Other stuff:
Also... try getting NorthFin Betta Bits, they're one of the best pellets with high quality ingredients, little or no fillers, and absolutely no nasty toxic preservatives. My bettas love them so much that they inhale them like it's drugs for a drug addict or something LOL (or exactly like Kirby)! https://www.amazon.com/Northfin-Food-Betta-Pellet-Package/dp/B00M4Q5DQ4/
Beware of overfeeding, which is equally bad for bettas (they are gluttons and would eat till they burst if given the chance) https://i.imgur.com/4RR2LZ9.jpg. (save this pic for reference, feed betta as much as makes his belly match between 1st and 2nd photo, then let him digest back down to a normal belly before feed again.)
Filter - any as long as it have adjustable flow (or else you can make a baffle if the flow is too strong, google about that), or many here recommend a basic Sponge-Filter to have a gentle water output that won't be stressful and push the betta all around the tank (the ones with big fins have a hard time with strong currents in their tank).
Heater - Any heater, following the 5-watt-per-gallon power rating rule, with a manual knob for setting temperature (so for example 5g you want at least 25watt heater), don't go for preset heaters (they're not very accurate). Bettas like 78-80F (25-27C).
Plants - Bettas like to have a lot (like a jungle) of plants to hide in, swim through, explore, play, and rest on. Some beginner live plants that don't require special setups are Marimo Moss balls + Java moss, other live plants may have special requirements in order to thrive. Silk plants (cloth leaves) are fine too if you don't have a green thumb. I do a mixed hybrid tank; silk plants + lots of marimo moss balls + java moss. Make sure if using silk/fake plants that there's no sharp pokey bits, remove and sand them down if there are.
Decor - Bettas appreciate cave-like decor that they can hide in. Make sure there's nothing sharp on the inside of the cave, nor sharp edges or sharp parts outside. Avoid also any smallish openings that a betta can get their head stuck in if they get curious. Another nice decor is the ZooMed Floating Betta Log (for 5g or larger tanks), bettas like hanging out in there.
More info on Betta care & needs: https://www.reddit.com/r/bettafish/wiki/index
If after reading all this info it seems like more than you can handle, you should try to rehome him on r/aquaswap to a local aquarist with a big planted tank to give him the best life. He’s a living creature and you have to consider his needs as you are responsible for his quality of life. If you want to keep him, then you absolutely have to give him the best care and best environment possible so that he can live a long healthy life (bettas can live 3-5 years and sometimes more if you really treat them well). When there’s a will there’s a way! You can and should do it!
Yea unfortunately a bowl is not an appropriate long term-home for any living fish. A 5gallon is the recommended minimum tank size to give your new gal pal the best possible quality of life... of course if you can give her bigger than a 5g, she will greatly appreciate it (longer rather than taller tanks are preferable to bettas). You can keep her TEMPORARILY in the bowl but you’ll need to change the water DAILY with fresh dechlorinated water (or pure spring water works too but is a bit more costly) since such a small container is going to foul up fast. Remove any leftover food/waste ASAP as soon as you see it.

Hi, and welcome to betta fish... and jeez people need to stop giving living creatures as “gifts” even if well-intentioned...glad you’re willing to do what’s right to give the betta a good quality of life.
Yes a 5gallon is recommended so good on you to be willing to upgrade him soon.. You can keep him temporarily in the half gallon but you’ll need to change the water DAILY with fresh dechlorinated water (or pure spring water works too but is a bit more costly) since such a small container is going to foul up fast. Remove any leftover food/waste ASAP as soon as you see it. A larger tank is going to be more stable and better for the betta in the long run. Some cheap ones can be had:
