Bathtub drain and w&O overflow connection

I'm planning on intalling a tub and using a pvc W&O. My question concerns how to connect the The 1.5" pvc pipe stubbing out of the slab with the tail of the W&O. I don't want to solvent weld the two pipes with a coupling just in case it has to be disconnected for some reason. Should I connect them with a rubber coupling (fernco...plumbqwik) or might there be some other solution that I'm missing? There is going to be a built in unit of shelves in the bathroom immediately behind the tubs wet wall, so an access panel could be build to inspect any mechanical joint. I want a joint that is going to be strong and am kind of stuck on what would be the best connection. Thanks in advance for any suggestion.

A trap adapter and slip joint connection is what is traditionally used, if your waste and overflow is tubular PVC.

If its Sch 40 PVC, then use a no-hub band clamp to join it to the PVC coming up from the slab. This connection is varmint resistant, and a fernco would not be. The band will also help stabilize the joint if there is slight misalignment.

I would definitely leave an access panel if at all possible. If you use slip joints, then the access panel is required by most model codes.
