I really like the new default theme, #TwentyTwentyFour, and I plan to stick with it. The cool thing about block themes is that any new features in the block editor automatically become new features for your theme too.
Who knows what #TT5 or #TT6 will bring, but my top wish is for #PostFormat support in the block editor/Gutenberg plus having post formats as a third taxonomy in #WordPress core.
The basis is already set with the slug /type/PostFormat. E.g. https://ma.tt/type/link/
