I’m running internet to an out building 550’ from the main house. I’m going to trench an run conduit with pull strings and fiber. Do I just get regular multi it mode with sfp+ connectors on either end? Will my normal 10g switches be fine? Anything else I need to think about?
Use single mode fiber. Something armored would be best. Like https://www.fs.com/products/70220.html or https://www.fs.com/products/155226.html
Then I’d use bidi SFP modules on each side. BiDi uses a single fiber strand for both transmit and receive. This will give you a spare fiber to use later for a second connection or if one of the strands were to break you could use the other one. You need one of each of these modules

Use something like https://www.fs.com/products/178413.html on each end to protect the connections. You’ll need a panel to go inside also. https://www.fs.com/products/35488.html
Grab a few of these in whatever lengths you need to go from the wall box to the sfp module in the switch. https://www.fs.com/products/40446.html
I’d go for single mode, since it’s usually the same price, if not cheaper. You’ll probably need a fiber splicing machine (and a couple or four splice protectors, depending if you use single fiber or duplex) and a splice box on both ends.
Use singlemode fiber G12 or G24.
You want to run 10 Gbps over the fibre? Then you need at least OM3 fibre with suitable SFPs (check the SFP datasheet when ordering)

Do you need to run high availability? If so, you may need to run additional fibres.
