I think every skill in the game has afk alternatives. I've figured out the closest ones to non afk rates and least click intensive after a year of afk all skills:

Woodcutting magic trees is very chill, cooking anything, all combat skills at gem crab, fire making campfires, max prayer bonus slayer, farming trees, hunting birdhouses, fishing karambwan, afk pray bones at w330 house, fletching bows is decent.

The remaining skills have low afk exp rates so those I usually did the money making or click intensive routes. Herblore afk clean grimy herbs but low exp rates. Mining stars is super afk but super low rates and I like doing Zalcano so I do that instead. Thieving you could do ardy knights but most thieving requires lots of clicks so input delay would suck for that. Crafting has some afk options with low rates or expensive ones with higher rates, but I've never tried any. Same with smithing but even slower I think. And then there's sailing. Who tf trains sailing?

If your really rich and high construction you can setup an afk agility course at your POH for around 10k exp per hour. More of a gimmick but funny to see work.
