Can be $$$ though. Screw on is cheap, and also doesn't leave multiple surfaces to catch dust.
So...
>my current lenses have 49, 55 and 58mm filter threads.Buy a set of 58mm and some adapter rings so you only need one set.
>does brand matter? Not really so long as it's decent quality. I use K&F and Hoya Pro.
>should i invest in 1 brand or does it not matter?Doesn't matter, they all use the same thread.
>uv is a must from what i read and saw. what about nd and single color ones?Variable ND if you're looking to take longer exposure in daytime.
Also red and yellow for better contrast on B&W.
I have a CPL permanently attached to all of my lenses because I almost always shoot around water, and after a while
I got sick of swapping them about all the time.
>for now i'm looking for the most useful stuff so i'm asking based on experience, which ones are usually the ones that get the most use.For me, CPL as above.
Red and/or yellow (not used together)
You can buy a set of K&F pretty cheap on the Amazon
Just get the whole lot in pic here and see what you like

With adapter rings on your smaller dia. lenses, shouldn't be an issue.
