As I also posted here:
I think it is best to go for option 2, however, give special status to wallets that are endorsed by the Grin core team, passed security audit (Grin++) community endorsed (Grin++, Niffler, IronBelly?).
So simply provide anyone who visits the main website with all the information we as community have on Grin wallets so they can make an educated decission themselves. I agree with @bluimes that it is good to list all wallets to not block innovation or alternative wallet solutions even though most people will go for secure wallets that are endorsed.
