Color calibration - I'm not entirely sure what would be involved here, TBH. "Professional" in this context would be what a pro home AV installer[1] would look for, not what a Hollywood color grader would need.
TV Tuner - Yes. An ATSC tuner with a COAX antenna input that can auto-scan for receivable channels. If this isn't feasible anymore, then I guess the HDMI input doesn't need ARC.
Connectors - looking at your photos, your input connections are on the side. If you put them on the bottom (down-facing), I think they'd be easier to reach if the TV is wall mounted (maybe not as easy if its on a table-top stand though). As long as they don't stick straight out the back, any orientation would be acceptable.
What's your experience with outdoor displays? 1000+ nits, IP-67 rated?
