try something really simple, like this
https://modrinth.com/resourcepack/simple-grass-flowers
all it does is add little flowers to grass-like blocks, it doesn't break the game in any way and it's a nice little visual addition that imo doesn't look weird and i'm surprised mojang haven't added something like this before

if you're unfamiliar with modrinth don't worry it's not all about mods, it has a large resource pack only section too which this is part of
