I'm building an indoor climbing wall out of 3/4" plywood in a finished
space. The wall will be well-secured to beefed-up framing. How do I
avoid rough edges/splinters, particularly at the butt joints between
plywood sheets?

My joint finishing options a
1) Do nothing, simply risk splinters (it's decent grade plywood)
2) Tape/mud as you would with drywall (I doubt it would hold up)
3) Leave a 1/8" gap and use some T-molding between sheets (not exactly
the look I'm going for).

I vote for #3, except that I'd use H-channel (overlaps sheets on both
sides), assuming that wouldn't interfere with the climbing function of
the wall. Not the look, no, and extra work and expense, but it would
certainly save the edges of the ply, which *will* get chewed up otherwise.
