This is the one proposed method that would double the stiffness of an I joist (plus a bit more for the solid filler). The other proposed methods are going to increase stiffness less than 100%.

I suggest once in the wall with a strap, once in the floor opening on the right with a strap, and then once by the toilet flange without a strap. The closet flange will secure that branch.

As long as it's a copper strap, should be fine. I still suggest omitting the strap by the closet bend.

I wouldn't think so, plus a strap (was thinking plastic plumber's tape) isn't super tight.

I like running a block below the pipe at the correct elevation, pocket or toe screwed to the joists at each end, and optionally strapped down to the block.

What's the idea behind the choosing a bend for your sleeve? The allowable curve radius on the lines can't be achieved within a 2x4 stud wall alone?

You'll get a better air seal, I think, if you...

P.S. Is that white layer visible from the interior the WRB? Meaning the WRB is applied directly on the studs, with siding over it?

Not sure I follow, sounds like you are listing two different options.

Worth bearing in mind is that the WRB is your primary line of defense against liquid water. The siding sheds bulk water but...

2x10s @ 16" o.c. can span a lot farther than 13'. So you have very strong and stiff floor framing (Deflecto says L/735 for SYP or DF in good condition, and that would be for a 50psf load).
