I live in the Dallas/Fort Worth area where I teach and shoot movies. I've won several awards including Best Cinematography (48 Film Project 2013).
You can shoot a lot for that budget, especially if you already have gear.
But what it really comes down to is what do you want to invest in, and your question is hard to answer based on the information you've given.
For example, a sci-fi film with a lot of effects is likely to cost more than a family drama or comedy. A one-day shoot will cost less than a one month shoot (and yes, some shorts can take that long, but it would be weird for a short to take that long - some features don't shoot that long).
All other things being equal, I would recommend offering your cast and crew at least a little bit of money - even offering $50 per day will greatly increase the quality of people you can find willing to work with you.
Save money for production design (things like props, set decoration, etc), makeup, and FOOD (craft services). I forget who said it, but I heard a director recently say that it's more important to spend money on what's in front of the camera rather than behind the camera (except for craft services).
Figure out your shooting schedule, figure out what you can spend on cast and crew for each day, with money set aside for production design, make-up, and craft services.
That's what I do, and it works pretty well for me.

LEDs tend to spike a little green - this is not new. Look at a cheap LED work light from Home Depot and it is very green.
Aputure is smart to add the filter - it is, in effect, a tiny piece of "minus green" gel. If you know what a minus green gel is, you know that it is a magenta colored gel - magenta being the opposite of green on the color wheel. Minus green gels are not new.
Heck, I've wondered if Aputure can create a small add-on piece for the 120d that is the same filter.
MrCheesyCam did his own test with these versus the Aputure Lightstorm 120t (mostly - it's not totally scientific, but he recognizes that) - https://www.youtube.com/watch?v=RR_d90Rgrq8
What is it about the UM4.6k that makes it hit your "sweet spot"? I just want to understand how you came to that conclusion before I respond.
Well, when you state that 2021 releases include "Gerald's Game", a film that was released in 2017, you loose a little bit of believability.
And while some of the "blockbuster" style movies are similar (Red Notice and The Adam Project, for example), there's plenty of other styles on Netflix, like Midnight Mass, Tiger King, and dozens of others that appeal to a broad audience.
It's almost like they want the most number of people watching as often as they can. Show Business, not show art.
