I appreciate the help.
mhegab:
Neither the router nor clients has internet access with the updated settings. I could try putting the WAN on its own VLAN, like yours, but I'm confused about the settings for that. For example, what proto would I use? I see yours has a username and password, which confuses me.
Correct, no tagging for port 0 in original config. My understanding is that when creating multiple VLANs the CPU port should be tagged so that it one can set it up to filter the data based on the VLANs of the data that passes through it (similar to https://forum.openwrt.org/t/vlan-inplementation/17470/12), which is why I tagged it in the updated settings.
Here's the screenshot of LUCI's VLAN page:
trendy: I think it does appear, but just to be safe, here's the output of that command (I put x's in places I thought might be security or privacy related):
