Yeah, all the camera options can be confusing, and I'm still learning myself. I'm more interested in the budget/DIY home-use scenario. I made an excel sheet of Point Grey Research's cameras, but I can't upload it to this forum, and don't have access to Google Docs while at work to create a sharable link.
In the below table are some of PGR's offerings. The color versions are the same price, so the one you choose would determine if you want to deal with 3 exposures for each color using a mono camera vs. having a full color camera taking a single exposure. I've filtered out anything with a rolling shutter of any sort. Some of these are the same camera, just different interface (USB3 vs. GigE), and some models from different lines appear to have the same sensor and specifications, so the difference is mainly the physical housing, I'd guess (i.e. the 2k and 4k options I've listed). There's other options beyond these models, as this is just a small sample.

Budget "HD" options. These should allow capture at the minimum HD defined resolution of 1280x720:
BlackFly GigE BFLY-PGE-13H2M-CS Mono 1.3 MP $265.00 1288 x 964 Sharp RJ33J4CA3DE CCD, 1/3", 3.75 µm Global shutter 30 FPS
BlackFly GigE BFLY-PGE-12A2M-CS Mono 1.2 MP $295.00 1280 x 960 Aptina AR0134 CMOS, 1/3", 3.75 µm Global shutter 52 FPS
Chameleon3 USB3 CM3-U3-13S2M-CS Mono 1.3 MP $295.00 1288 x 964 Sony ICX445 CCD, 1/3", 3.75 µm Global shutter 30 FPS
BlackFly GigE BFLY-PGE-13S2M-CS Mono 1.3 MP $345.00 1288 x 964 Sony ICX445 CCD, 1/3", 3.75 µm Global shutter 30 FPS
Blackfly USB3 BFLY-U3-13S2M-CS Mono 1.3 MP $345.00 1288 x 964 Sony ICX445 CCD, 1/3", 3.75 µm Global shutter 30 FPS
2K options. 2K can be defined as 2048x1080(for film/video production) and most current "Full HD" tvs almost reach this as their resolution is 1920x1080:
Chameleon3 USB3 CM3-U3-31S4M-CS Mono 3.2 MP $465.00 2048 x 1536 Sony IMX265 CMOS, 1/1.8", 3.45 µm Global shutter 55 FPS
BlackFly GigE BFLY-PGE-31S4M-C Mono 3.2 MP $495.00 2048 x 1536 Sony IMX265 CMOS, 1/1.8", 3.45 µm Global shutter 35 FPS
4K-ish options. 4K can be defined as 4096x2160(for film/video production) and 3840x2160 (4k tv resolution):
Chameleon3 USB3 CM3-U3-50S5M-CS Mono 5.0 MP $735.00 2448 x 2048 Sony IMX264 CMOS, 2/3", 3.45 µm Global shutter 35 FPS
BlackFly GigE BFLY-PGE-50S5M-C Mono 5.0 MP $795.00 2448 x 2048 Sony IMX264 CMOS, 2/3", 3.45 µm Global shutter 22 FPS
For film, we're mainly concerned with the second dimension since the film frame isn't as wide as an HDTV screen. I'm guessing some of these cameras may not have a "widescreen" aspect ratio, but I haven't looked that much into them.
