Best side hustle for evenings/weekends?

Looking to pick up maybe $500-800/month extra. Kids are 7, 4, and 2 - so evenings are chaotic but doable after bedtime.

Considering: freelance writing, tutoring online, or maybe Instacart/DoorDash type stuff.

The tutoring appeals to me most (only worked til like 8pm, still home) but writing feels less "ugh I'm tired" at the end of a work day. Anyone doing any of these? What's the realistic time commitment?
