Q: can this be used in-between cement joints in a walkway?

Sika’s self-leveling sealant (and backer rod) is the most appropriate product for that situation. The backer rod prevents 3 point adhesion, which you should look up before performing this job. Self-leveling sealant will flow downhill if used on a slope, so the construction sealant might be a better choice in that particular case.

Q: If used to fill gaps between tiles, how does this (polyurethane) compare with epoxy grout ?

This has a silicone texture, I will use it in for the outdoor area. I would not use this to fill gaps between tiles, you should use epoxy grout especially if it's indoor.

Q: Will this adhere to asphalt for the crack between driveway and cement apron? I’d rather use a weatherproof flexible sealant than asphalt cold patch.

It should! This was recommended by the company who raised up three LARGE concrete patio slabs. Unfortunately, the slabs had all moved in different directions, letting water sit up against the foundation. Once raised up, with settling of earth underneath, a couple of the slabs cracked. I used this sealant to fix those cracks. It's remained in place through two Pacific Northwest (wet) winters. It's remained flexible, keeping slab pieces together with no slippage. Good product!

Q: Can I throw some sand on top of horizontal morter cracks after applying the Sikaflex to give it texture?

I think you can. Think of it as a kind of epoxy. If you throw some sand on its surface before it dries, the sand will end up imbedded in it.
