There are a lot of sets of rims and tires from CLA's, A and B-Class MB's in my area.

Do these fit on the GLA?

The stock GLA rims are 7x18 ET46 (or 6.5X17 ET38)

A lot of the A, B and CLA rims are 6.5x17 ET49.

Offset calculators and backspacing seem to suggest they will be fine.

Anyone have any experience?

I don't have any experience with same but given that the GLA is a crossover-SUV and therefore has larger wheel wheel openings than the CLA sedan they should fit fine. However I'm not sure if the front brake calipers are the same for CLA-GLA so do confirm that positive offset will afford interior spoke clearance in particular.

I believe the tires themselves are larger on the GLA then the sedans. So not sure, and even if they do it might lower the car in a weird way. I wouldn't do it personally.

Thank you for the replies.

I checked out https://www.wheel-size.com/size/mercedes/gla/2020/ and they show what factory and OEM rims fit.

Ended up finding a set of OEM rims made for the GLA with the right tire sizes.

Well done. Manufacturers spend a lot of design effort matching rims/tires to their vehicles and you can't miss with OEM spec's.
