I've heard these offset sockets get more leverage. They have that freeze spray (wart remover in a bigger automotive spray can. Soak with penetrating spray overnight?
The top of the strut shaft should have something you can put some kind of wrench on. Sometimes it's a small hex section you can put a small 3/8 drive socket on. Sometimes it's a hex socket for a hex key/"Allen wrench".
What size is the nut? If it's 22mm (7/8"), you can sometimes use an oxygen sensor like this one https://amzn.com/B00390BS7C to turn the nut while holding the shaft from the top. Other times you can use an offset box wrench and hold the top while you tighten it.

We need to make sure your wiring harness is not damaged/chewed by critters before making that call. Wiring repairs generally aren't too hard if you know how to properly cut and splice. The O2 sensor is only 4 wires. The sensor itself is only held in by the threads, so it's as easy as unscrewing the old one and screwing the new one back in. Sometimes these oxygen sensor adapters for your ratchet can help a lot for loosening the old one since it can be on there pretty tight.
