Hi Kyle,
there is no secret sauce in this industry, footage that is the result of the director vision and dop job on set is the king.
Good film look can be achieved using resolve luts that comes for free, some other good alternatives are:
Filmbox (like the halation, you can tweak it a lot and in HDR works great)
Ravengrade Luts/DCTLs
Dehancer
Cinegrain FILM Pipeline (built for aces cct)
Juan Melara luts/powergrades
These are all valid options that I personally tried, you can also do amazing grades without using any magic lut, avoid free luts from web they can easily break.
Have a look also at DCTLs, there are some free and some paid, some of them are similar and you can download a demo to check the differences. Those that pop to my mind are MONOnodes, KH, CullenKelly, PixelTools
