MAPLE or SPRUCE may be stronger.

How wood you know?

That should finish this.

I'm in the construction business, so I mite (is that the best I can
come up with?) know this sort of stuff.

Er, seriously, engineers insist that kiln dried spruce is stronger,
but it sure is brittle. IME, hem fir has proven itself to be much
tougher, and I've yet to load KD spruce in any direction where it's
stronger than hem fir.

I hope you aren't board (hah! better...) of my lumbering (woo hoo!)
prose.

Loaded longitudinally, tangentially, or radial to the grain?

In my experience, all of the above, in compression, stretch, span,
beam, whatever types of loads. I've just not had a real-world
experience where KD spruce has survived more load than hem fir.

All combinations of the above loads do happen, between cutting,
nailing, screwing, loading, removing, breaking, and all the other
things you do with wood. I've used both species as parts of walls,
staging, makeshift tools, pavement protection under heavy/sharp
stuff, tables, and as ultra-rough-service boxes.

What have I started? I'm sorry I asked ;-)

OTOH, bamboo really has been used, especially for track. Evidently
someone decided then to try to make bamboo bikes, but those didn't
work out so well.
