Sounds like you want and should keep your options open.

Go for something with hotswap and as much switches as option possible so standard over something like opticals.

If you dont game, id say something that w bluetooth. You can still flex a good coiled cable even if its BT/wireless. Unless you go for the super rare wireless charged keyboard.

And if you game, youd want to ask one of those osu crackheads with a brazillian PP or what they call it. (as far as I know they and we shooter folks love the wooting but thats a 60%... god I wish it was a TKL so I can replace my HE2 with it. Wooting please)

If you dont game, there are some lovely and cheap mods you can do, that saves money for switches. I for example work on a custom with clicky zeals, the second best clicky after alps in my honest opionon.

If you are a casual gamer, any board with gateron reds or yellows will do. You just get the typical upgrade kits with lube, bandaid mod and stuff.

You gotta kinda know what you want at the end of it all do know if you need a cheap basis or if you can go balls to the walls.
