should I leave the settings in the Netgear on Router mode?

Yes.

@Paul_Elliott

provide greater customer connection security

ummm “no”, but that’s my opinion.

@Paul_Elliott

enhance the use of the limited number of IPv4 addresses remaining on the internet

This is the real reason and this is why more and more ISPs will start using this until IPv6 is more widely deployed and in use.

possible to get port forwarding and VPNs to work with CGNat

VPNs yes. Port Forwarding absolutely no. Not without the ISP putting rules into their CGNAT infrastructure to forward inwards to you.

If you want to avoid the $10 then look into some of the great write-ups others have done here for getting VPNs working. I like the Tailscale solution personally although I don’t use it.
