I'd go with LEDs as they're more power efficient, something like a T8 style. Something like these?

These are the ones. In theory if you feel comfortable modifying the design you could modify the light holder files to fit just about anything but I would want to make sure the lights were not heavy would be my only advice I think.
You won't typically find good grow lights advertised with their lumen rating, as lumens are a measure of apparent light to the human eye so they aren't particularly relevant to plants. Grow lights are generally advertised by their wattage, PPFD maps, and PAR. These are good entry-level lights, and would give 4 trays a great amount of light, 8 trays a decent amount of light, or anywhere in between.
Here's an amazon link for the ones I bought. They're pretty bright but my plants have been thriving since I installed them about 6 months ago (I think) https://www.amazon.ca/dp/B0811VX52Z/ref=cm_sw_r_apan_glt_i_dl_EPH0MMQP98P0WVB54AXE?_encoding=UTF8&psc=1
I bought 2 of the short version of this cabinet and have my indoor setup in them. I have 2 mini desk fans running constantly in them, removed the side glass panels off of the sides that face the opposite cabinet so that there is air flow through the space between but not too much humidity loss, and have these lights stick on with outdoor command strips https://www.amazon.ca/dp/B0811VX52Z?ref=ppx_pop_mob_ap_share.
I get temps up to 28c and 50% humidity which my hot peppers love. They are flowing since bringing them in 1 month ago. I'm constantly pruning because the space is very small, but the plants are thriving!
I hope this helps!
I have 24W LED strips:

I used two per shelf.
I don't think my setup for lights is worth copying - I had already printed the top cap for my tower and didn't want to reprint it, so I just whipped up a quick design in Tinkercad for arms that I could attach by drilling into the cap. The LEDs attach to the arm via a clipping mechanism so they can be swapped out easily. You can probably see how the lights are mounted from this older picture. If you really want to use this design, let me know and I can dig up the STL, but it has a lot of aspects that could be improved. https://media.discordapp.net/attachments/172824185981108224/1032321585157251122/unknown.png?width=672&height=896

I run the grow lights for 16 hours a day and the pump for 5 minutes/hour via a smart plug. Also, if you get different lights, I highly recommend the app Photone. It'll let you approximate the DLI/PPFD using your phone camera. Probably not precise, but seems good enough for ensuring that you're at least close to the requirements for what your plants need. Happy to answer any other questions you have.
T8 LED grow lights, exactly like these. I will be starting seedlings in a smaller tray with a much closer light so they are not leggy.

What a neat courtyard area, "very European" was my first impression, thanks for confirming :)
First, I am hopeful you won't need added heat, considering lights will provide some. You can also start in a storage rack which can be wrapped with some form of sheeting, to further contain heat to the grow area, effectively creating a grow tent. Reflective sheeting, like mylar "space blankets" can help contain light as well. Additionally, you might want to enclose the doorway(s), something a simple as a weighted or magnetically closed curtain, would help keep heat from escaping. Added bonus if you choose to keep light from escaping, see note below regarding lights and neighbors. You can also time your lights to run primarily at night when temps are coldest to make best use of their heat. Also remember heat rises, so the upper area of your tent will be warmer than the bottom, and the hottest spots will be the back side of the lights.
Speaking of lights, I am very happy with the Barrina/Kihung light strips. https://www.amazon.com/gp/product/B0811VX52Z/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I do suggest white vs pink lights, not because one grows better than the other, but the pink lights run at night might attract unwanted attention from neighbors. If you want better mounting clips for these lights, you can find them here https://buddiy.net/product/24-barrina-wire-racks-light-clips/ Be sure to use a timer to automate the on/off cycles, as much as you think you'll remember to do it yourself, it is practically guaranteed you will forget. :)
As for the hydroponics, youtube is your friend. I did a quick search for a range of examples. A simple manual setup here https://www.youtube.com/watch?v=tY7-Bg5DERY with the mistake of using clear containers. A more complex (overly so IMO) automated system here https://www.youtube.com/watch?v=B9amRufYA1c but the series of videos is quite instructional. IMO, in both cases, the plants should be spaced farther apart. I suggest starting with a manual system, then after you have some experience, decide if/how/what you want to automate.
For seed starting I recommend the Park Seed Bio Domes. They are engineered for the job, and small enough to keep indoors where you can monitor them frequency.
Good luck out there!
I use 2-foot lights a lot and have found these work well:
They are 24 watts per strip; the Barrina you linked are 10 watts, which seems a bit low. I've attached them under my shelves with this removable and reusable silicone tape, and as long as I use at least 6" of tape, they stay up.
There’s a link to a pic of the set up above! I use kihung lights.
I just got these, but also have some 13 inch ones.
