I am a web developer who has a fair amount of experience building my own sites using HTML CSS (and some extra JS/PHP when needed) from the ground up.

Recently I have been starting to learn and practice in wordpress much more.

My question is: is twenty twenty four default theme a child theme I create good enough to make almost any website I want for the most part? Does it give enough flexibility? Is it almost totally customizable?

Or is there a better theme combo for someone who has HTML CSS web development experience? I know it's probably subjective what is "better" but I'm looking for flexibility and development potential. I don't want to be held back by the first theme I use and then 6 months from now have to switch up my theme completely (unless that's easy once you have Wordpress experience? I don't know).
