Home Relays to store all your content. nostr.wine and relay.tools are good paid options. You can also use free relays: nostr.mom , nos.lol , etc
Relays to store all zaps, likes and replies to your content. They might be the same as home relays if those home relays do not require payment to post. Nostr.wine would not be a good option here.
Relays to use for DMs: Here you want a relay that anyone can post to but only you can download your messages. inbox.nostr.wine is a good option. Advanced settings on relay.tools personal relays can also store your DMs.
Private Relays are for things no one should see, like your Drafts. There are no dedicated relays for this category yet, so I would use a local relay like Citrine.
Search relays: hit the Default button to use all available options.
Local relays: use Citrine.
General relays. Delete those that you moved to their specific sections. Keep everything that can help find events from your follow list.
