You are in the same boat as many new users to RAW work flows and this subject comes up a lot. If you do a search there are many options discussed.
First off, no disrespect, don't confuse colour correcting and applying a "look" as grading. Grading is so much more than that. It's an art form in itself. It involves leading the viewers through the scene and enhancing the story telling process. This is where Resolve really shines and where the talents and skill of a good colourist come in. Learning to use the tools will open up many more creative options it bringing your footage to life but it takes time understand and years to master.
I have huge respect for colourists as they can really make a story come alive.
But back to your needs. You are looking for a simple way of colour correcting your footage and applying a "look". This can be done in many ways. Most NLEs offer great tools to do so but don't support Cinema DNGs.
If you have Lightroom why not simply import the DNG sequence into LR like you would import stills. Colour correct a single frame and apply those settings to all the images in the sequence. You then export the images sequence as TIFF or JPEG and import the sequence into your NLE.
If you have After Effects you could simple import the sequence directly into AE, process it with CameraRAW then work on your look there.
