Parks maintenance - basically clean the parks of leftover foods, dog poo, forgotten clay tablets and clay clumps, clean around dustbins, collect the leaf piles in autumn, shovel snow in winter, plant new trees and harvestables, add new playground equipment, fix anything broken, etc.
Bike shop repair - fix some broken spikes, oil the chain, add new alarm bell to it, change tires, etc.
Street portrait/caricature artist - sit in a park and wait for customers to paint their portrait or caricature for a fee
Private piano or violin teacher - have children or adults come to your house for 1on1 lessons
Professional darts player - you play darts a lot and train for tournaments and occasionally take part in rabbithole competitions and maybe earn a title or something
Gardening - I loved how we could trim the hedges and roses in TS2, would love to have something like that back. We basically can't have an active decorative garden right now, only for vegetables and those lame flower bushes.
