npub1v52eyrdqpzcs7mlsqxamlq4j93xyc3ht3rsqxxepssv0h2s9r6yst2qu8a (npub1v52…qu8a) I have the same setup, although it’s more like 200 feet in my case, and it’s two outbuildings in two different directions. In one case, I use powerline Ethernet, which I somehow get gigabit out of, to my great surprise. In the other (my office), I trenched conduit with cat6. I had to trench power to that building anyway, so there was no avoiding the expense.
If I were in your shoes, I’d start with powerline Ethernet. Folks will suggest WiFi, but I don’t recommend it.
