Not sure how long you need. But have you thought about using a Direct Attached Copper (DAC)?
I bought one of these:
https://www.amazon.com/gp/product/B00WHS3NCA
And used it to connect my Ubiquti EdgeSwitch-8 to a Mikrotik switch. Worked just fine and is running at 1Gbit/sec as the switches only support SFP.
I setup a peer-to-peer 10Gb network between my 3 servers (R410, R510 & R710) using the Chelsio dual-port cards (https://smile.amazon.com/gp/product/B00O1M9UOA/) and these cables (https://smile.amazon.com/gp/product/B00WHS3NCA/). Works like a friggin' champ. I already have a GB switch for the LAN and those three boxes are the only ones that would truly benefit from 10GB so I didn't see the need for a 10GB switch at this point. I'm pondering moving my office to the basement in a room next to my server room and if I do, I'll throw a card in my desktop and add it to the peer-to-peer network.
Get a couple Mellanox ConnectX-3 cards. You should be able to get them on ebay for $35 or less each. A lot of people use x-2 cards, which you can get for much less, but they are no longer supported (by Mellanox and the mlx4 drivers). The x-3 cards are still fully supported and you can still get firmware updates. I'm using MCX311A-XCAT cards between freenas and linux and I have no problem maxing them out. That model has SFP+ connectors so you can connect them using a DAC cable. I use a cable I got on Amazon.
EDIT: Another thing to be aware of when buying used cards is the bracket height. A lot of them come with SFF (short) brackets. You may need a tall bracket instead.

I have one of these and it works fine. Just select the Ubiquiti option and then whatever length. I am using it between an 8 port POE and my 16-XG. You have to select 1Gb on each end, same as with optical SFPs.

Yes that’d work fine. I believe there is an issue now with the UDM Pro not being able to autonegotiate a 1Gb connection so at the moment you’ll need to specifically change that port to 1GB but it should be something a future firmware will fix.
I am using this SFP DAC cable from my NAS to the USW24 Pro and can confirm it works great as well, and is available in many different lengths:

If you're just doing a short connection, consider Twinax Direct Attach Cables (DAC) -- usually around $30-$50 apiece and all one piece, no separate fiber + transceivers. Also look at 10gtek as a manufacturer. You can find them in Amazon and they have compatible versions of basically every item for pretty much any manufacturer, for very, very cheap. Examples:
