What is the measurement from center to center of the two strike holes?

5 3/8" however, the strike holes are oversized (1 3/4") so there is quite a bit of leeway

How thick is the plate?

Upon measuring, it appears to be 1/8 of an inch thick. It feels solid.

recommended screws? I'd like to use some quality screws but have no idea what to look for, brand, size, etc

Comes with some very well impressive screws so no need to worry. You are in good hands with this baby. I tried as best I could to kick it in and was rewarded with boot marks and a trip to HD to get a solid wood door. Any unwelcomed intruder would need a some serious tools to get in. Make sure your locks are unpickable too. Check this outFlip Guard Satin Nickel https://www.amazon.com/dp/B00HZD8S8G/ref=cm_sw_r_em_apa_a1KOzbA6T37Y1

Will this work on a interior door frame which is not 1 3/4"?

No too wide..will work on 1 3/4 but not on 1 3/8. Not unless you trim the door stop
