My 3.0 MFI build has been extensively documented on this forum. Right down to how I re-profiled the space cam (from a 2.4 "T" pump) to accommodate its differences in fuel delivery requirements.

Just weld a bung onto the exhaust for the sensor and run the wires to the dash or glove box for the meter.

Absolutely. A wide band O2 sensor with a way to record A/F over the full spectrum of operation is a must for any real serious MFI tuning. I used the old Innovate Motorsports LM1 and found it invaluable. I run thick flange SSI's, which come with the bung already in place. Lacking that bung, a tailpipe clamp can also be used.
But, tuning for an altitude change? I don't think doing that level of deep dive is necessary.
