What if I want my devices visible on the public internet? Then I'm tied to my ISP's addresses. Or, I have to maintain both addressing schemes

That's why I mentioned multiple addresses. The public addresses (assigned using SLAAC or DHCPv6) are for global reachability, while you use the local prefix for stable addresses within your network.

If you want stable global addresses, you should request an AS number and prefix, and choose a provider that allows you to announce it with BGP.

This is also the case with IPv4.
