Sealing with spray foam?

Is ok to use spray foam to seal the gap between the sleeper (or 2x4 stud) and rigid insulation foam?
Forgot to mention: it is for floor, slab on grade with sleeper

Is it ok to install fiberglass insulation between 2x4 studs resting on sleeper?

I am preparing the sleeper with 2x4 studs on top of sleeper. How to insulate?
Already put vapor barrier, some rigid insulation foam between sleepers. As there is 2x4 studs resting on sleeper, it will give some rooms to have another layer insulation if possible. Thinking to install faced fiberglass, is it ok?

TJI floor joist framing for bathroom tiles and curbless shower

Will start to install the floor joist soon, floor joist on pony walls.
But bathroom will have tile floor (3/8”), and also have curbless shower.
The main floor is LVP floor.
Is it necessary to lower the joist for bathroom and shower area, how many to drop for each?

Sewer line design

Running a sewer line for bathrooms in garage area. Grade is from left to right (see pic), but need to run pipe from right to left (red color) for sewer to main.
An idea is make two 45 transition in the middle, the right side is on slab and left is under slab, due to grade.
Any suggestions for this connections?

Sleeper on SOG

Need to add the sleeper on SOG to match the main subfloor.
Here is the idea:
Vapor barrier on SOG
2x4 pressure treated on vapor barrier
Then add 2x6 on the pressure treated,
add the rigid foam between 2x6 as insulation, leave the space between 2x4 treated clear

There is a small hole (1’x0.5’) in the side wall to crawl space, is it possible to have the air flow to avoid humidity in the sleeper?
