I have a lighted sign on a commercial building that I need to meter so we

usage?

What's the supply voltage/phase?

Where's the connection(s)?

There are ways depends on what it is and where, etc., as above.

Alternatively, it's possible one might get an estimated usage and then
simply count operating hours and be close enough.

Yeah. If it is on 24/7 you could ball park it pretty close.
You need wattage and power factor. At the breaker(s) you can take an
amp meter and get it pretty close.
