While I agree with the OP that more choices would be good, Analysis Paralysis IS a real thing. 5e suffers from it a lot now which is why many veteran players complain about power creep and many DMs flat-out ban some spells, races, or subclasses.

I want more races, classes, and subclasses. I also want the game to go all the way to lvl 20. However, I accept that there are limits to what developers can do.

I'm a very tactical D&D player. I literally research how to make THIS spell work well with THAT maneuver because IMHO real people would do that if they knew that not doing so might kill them. However, many players are more casual and I don't think that they should be punished for having a more 'that sounds like fun...let's try it!' playstyle.

As for more always being better, tell that to a person who is drowning...
