Right? It's a lot... Thankfully, Amethyst provides some decent direction and sensible defaults, especially for DM inboxes and Search relays.
You don't have to worry about the private relay or local relay lists unless you are running your own private relay or Citrine.
Just focus on Public Outbox, Public Inbox, and General Relays.
Well, sir, you currently have 18 relays on your inbox/outbox list, with ALL of them set as inbox relays, and 9 of them set as outbox. That's a bit excessive. At max, you should have maybe 4 outbox and 4 inbox, and there can be overlap for a total of 4-8 relays.
This does not mean those will be the only relays you read from or write to, just the only ones you are announcing to others, "Hey, find my notes here!" and "Hey, send me replies and reactions here!"
You also have a number of paid relays. You don't need that many. Pick two.
So, for your Public Outbox relays, I would go with:
1. Major Public Relay. Something like nos.lol or nostr.mom from your existing list.
2. Paid Relay
3. Any other relay with good response time.
4. (Optional) Major Public Relay
Then comes the Public Inbox. Here's what you want to get it pared down to:
1. Paid Relay (Same as outbox)
2. Paid Relay (Typically don't need to pay just to read from it)
3. Web-of-Trust Relay
4. (Optional) Web-of-Trust Relay
General Relays are where you can add some other relays you want to write to for reaching users who are on clients that don't support the Outbox model yet. This is why Amethyst conveniently offers you suggestions based on what relays those you follow are using. Again, though, if you add any public relays here, make sure you set them to write only by having the upward facing arrow lit up green while the downward facing arrow is grayed out.
If you want to add some specialty relays, such as writing to hist.nostr.land for keeping backups of your follow list, or reading from purplepag.es so Amethyst is likely to find their relay list, you can add them in this section, too. I also have a couple additional WoT relays I read from that are added here as read only.
