Welcome!
A Stick purchase, especially if ordered new from Stick Enterprises, can involve so many variables that your head can spin...analysis paralysis definitely lives here.
It also doesn't help that some of the used instruments out there, that might be worth considering, are over-priced. As part of your research, be sure to look at sold instrument data, which I believe Reverb.com can provide.Generally speaking, when considering used instruments: IMO, if there's one feature to use as a litmus test, it's the adjustable truss rod. After that, again IMO, it's the adjustable "3D" bridge, which lets you adjust intonation and provides flexibility for changing to different string gauges (ie light/medium/heavy).
Other tidbits: a well set-up Stick holds resale value very nicely. If you spend money on a good instrument, new or used, you can probably get most or all of it back if you decide to sell it and get a different one. Finally, a well set-up Stick, even if you eventually decide you want a different configuration, is still going to be awesome to play. Assuming it's in good condition, "This was a terrible purchase!" isn't something I've ever heard someone say about a first Stick.
Shameless plug for the Tap In Time podcast...we did a pair of episodes aimed at the first-time Stick purchaser not too long ago that might be helpful. The first took it on from a philosophical standpoint, and the second dived into some of the specific details/options.

Enjoy the journey, it's a wonderful instrument!
