CAT6A is ~$0.25-0.50 per foot
Bend-insensitive fiber can be $1-2 per foot (though sometimes less if bought in bulk).
Generally though CAT6A has a minimum bend radius of ~6-8x the outer diameter of the cable.
Regular fiber optic cable has a minimum bend radius of ~20x the outer diameter of the cable when under tension, and ~10x the outer diameter when slack.
Bend insensitive fiber can have a minimum bend radius of ~2.5x the outer diameter, but it will vary depending on the specific type of bend insensitive fiber, cheaper BIF would be more like ~3.5-5x the outer diameter.
So a 2mm diameter cable would need ~20-40mm bend radius using a traditional fiber cable, but could be as low as ~5mm if using high-end BIF cables.
CAT6A assuming a ~6.7mm outer diameter cable would need ~45-55mm bend radius.
tldr; CAT6A has a similar (or even slightly larger) bend radius requirement since the cable is generally ~3x thicker than fiber.
Though it's significantly cheaper than BIF fiber, so unless you NEED super tight bend radius, CAT6A is still probably the best choice for a home network.
