I want to branch out from PLA. Should I try ABS or TPU?

TPU will be nearly impossible for your kiddo to destroy. ASA/ABS are rugged, but if your print has thin surfaces it's less strong in my experience than PETG.
I didn't find TPU hard to print personally, just go slow and turn retraction way down or completely off. It will string pretty good, but most slicers have a setting to avoid crossing perimeters that will keep it in check. The only thing I would be wary of is ending up with a floppy print, so make sure the part has some structure.
Don't forget about material wear due to UV radiation. ASA is good for outdoors projects, rugged, not as toxic and UV degradation is minimal.
