Where are you planning to use sealant? It's the materials that usually dictate which adhesive to use...

Teflon tape is advisible when you want to remove tapered pipe threads at some point in the future.

Hose Clamps are not usually necessary, but I like the plastic total circle types.

I am not a fan of massive globs of silicone for any reason..., but I understand that some people do not have the knowledge, skills. tools, or money to do the job correctly.
