Most of the second and third words are either the first tone or the forth tone. You can check the pronounciation of words here: https://play.google.com/store/apps/details?id=com.nesnet.android.cantonese
Using g board to input the word with jyutping should be easy, as the video has shown all the jyutping under the word.
Do note that some of the words are not well supported by jyutping. You will need to handwrite some words like "黚".
Hiya!
I have quite a similar background to you. I went to Greenwich Chinese Community School in London back in the day and took the lessons half-seriously, since I only spoke Cantonese at home. I remember one time I heard some older students use Cantonese during recess (whereas other kids would just use English) and thinking it was cool, finding out later that Headmistress Chan had given them incentives to do so.
Technology has worked wonders for language learning, and especially for heritage speakers like us where we can easily get the hang on vocalising and grammatical understanding.
I have now lived in Hong Kong for almost seven years, and I use Chinese in writing daily, although I still find it easier to read and write in English. I use Chinese when talking to people via whatsapp, and I also have to read it when getting around.
So I guess being immersed in it really helps, and trying to use it in daily situations. When I first moved to HK, if I was confused by pronunciations I'd use various apps and websites to help me out. Some faithful resources I've employed are CantoDict, with the correct jyutping so you don't confuse yourself with ghetto jyutping, and Cantonese Phonic app by Superlubu (which makes use of the Chinese University HK's Cantonese Database). With these two, whenever I would come across a word I'm not familiar with I'd use Chinese Handwriting method on my smartphone to input the character and then get the pronunciation from Cantonese Phonic and a more comprehensive dictionary explanation from CantoDict (Cantonese phonic also has dictionary meanings, but it is very concise).
Recently, I have come across Cantonese English Dictionary and Translator by EPlus Moment, and it seems to be quite extensive as well.

As for actually implementing technique into improving your Chinese, I would have to say that it does require real, human interaction. There are discord servers, but I don't recommend solely relying on them, my experience of them was just a bunch of Chinese diaspora that didn't really engage using Chinese (when I typed in Chinese in one of them I got told off) and just used it as a normal culture sharing server.
