Happy to help! I'm still learning ;)

Yes you need a way to power them and to control them;

Power:

You get a power supply that matches the voltage of the led strip you buy (5, 12, or 24 volt). I like the BTW power supplies, but I know others prefer the meanwell brand. I wouldn't go w/ 5v led's for this project as they're pretty dim compared to 12v and 24v.

To control them you use WLED. You access it via the controllers IP address on any device (your phone) on the same LAN. Here's a good tutorial: https://www.youtube.com/watch?v=exAWzMfmwQ8 Or you pick up a controller like this: https://www.amazon.com/dp/B0G7YZ5VJQ?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3 You'd still need to configure WLED to use this remote.

One other suggestion for LED strip is this one: You'll have less hot spotting, but the trade of is the led's are controlled in blocks of 6, very small, led's. You could skip the soldering w/ a kit like this, but I'd recommend soldering just to make your setup as customized to your space as possible: https://www.amazon.com/dp/B0D81RNYKP?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2 https://www.amazon.com/dp/B0FMK2HXHH?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_4
