I didn’t buy a kit. It’s just stuff & tools etc that I have acquired over the past 20 years or so initially for working with musical equipment guts.
Thinking about what I use and touch every time on my bench is below.I know you said that you have soldering stuff but I’ll add this for other people reading.
Cheap soldering & hot air station: I bought this one:

No brand snobbery here - this is cheap MIC and does exactly what it advertised it would do. Get past the Engrish manual, and it has done its job very well.
solder snuffer: desoldering guns are very useful and a lot of folks use electronic ones which are fine. I use one of these cheap manual ones.
$10 bucks and will snuff the solder out lol. I’d probably pick up an electronic one but I don’t have the space on my bench for it lol so the manual one works great for me.
Solder braid & Flux: this stuff is very useful so buy some if you don’t have it. I use a paste and brush but the syringe applicator is very useful and easier in the beginning imo.
Cheap, and very useful!
Small electric fan: Don’t breath in those solder fumes lol. Have a cheap fan to keep those fumes out of your face & lungs. Something as small as a simple case fan wired up do the trick.
Electric screw driver: I have one similar to this and it works fine for most of my needs. it’s larger than popular stribeto but I use it for more than just computers lol
here’s the stribeto
Spudgers and doodads: For an immediate assortment of electronics spudgers and tools, I like the look of this one
Under $10, not too big, has an assortment so you can see what you like and it has one of my fav thin metal spudgers which is a handy bit of kit for me anyhow. From there you can see what you like and buy accordingly. Truthfully though, so many kits come with spider/tools nowadays, I have drawers full of them at this point and so will you eventually LOL
Small micro screw driver set: I use one I picked up from harbor freight for like 8 bucks but this one on Amazon is nice and it comes with an often over looked bit of kit - the ringed suction cup. You don’t use em every day but when you need one, they’re invaluable to have in your kit.
Long torx wrench set: I like Powermac G5s and I am in them often and you need long torx 15 to get those heat sinks off and t10 to get the lobo off and access to the northbridge heat sinks. I have this set that is both magnetic and long from t10 to t30.
Very useful and a set you’ll have on your bench for the rest of your life assuming your kids don’t steal them for light saber wars.
Dorkus Maximus magnifier goggles+ light: I have one of these and they make you look horrendous BUT they do their job when you’re working on something tiny and you need additional illumination.
I’m sure there are some other things I’m not thinking of but this is what I’m most commonly grabbing for.
