So you'd rather write firewall rules so that people using your "guest" side
of the *bridged* network stay out of the *other* side of the *bridged*
network?  (Hint:  What does "bridged" mean for where packets go?)

If you have the ability to set up multiple subnets, it's easy:

Subnet 0 is wired local ports on the back of the router
Subnet 1 is your local 2.4ghz wireless
Subnet 2 is your local 5ghz
Subnet 3 is your guest 2.4
Subnet 4 is your guest 5ghz.

Subnets 0 1 and 2 can talk to each other,
Subnets 3 and 4 can only talk to the outside world.

Probably want a few more subnets for all the crapware that's shipping as
part of the Internet of Pwned Things.

Or you can try to do all this in one bridged subnet.  Have fun with your nervous breakdown. :)
