If you watched the film "Happy Death Day" (if not the lesser sequel) and enjoyed its exploration of a kind-of goofy mashup (Ground Hog Day x Teen Slasher), the same director made a film built on, roughly, a similar concept, just called "Freaky". If you already suspect you might like it, don't read anything and just watch, though you may be able to guess the mash-up from the one-word title. It's fun, and well-made.

I'm struggling to think of much else that I've personally seen, from last year, that wasn't a little too indie or "genre" for me to recommend it to someone whose tastes I don't know—I didn't get much new watched, and mostly caught up on some reputedly-great stuff I'd missed from the prior five years or so (I keep up with a mix of pop junk food films, which I do like, and the "good" stuff, but usually don't have time to watch anywhere near all of either) aside from some fairly taste-specific newer material I watched.

Some other titles I'm seeing, from people I know and trust, for 2020, include: First Cow; The Old Guard; Portrait of a Lady on Fire (technically a 2019 film, but widely available in 2020); Wolfwalkers (animated); Spontaneous; Bacurau; Blow the Man Down. There are lots more, that's just a varied sampling.

From what I've seen released from 2020 onwards I've particularly liked:

Black Bear, Possessor, Palm Springs, Love And Monsters, Psycho Goreman, Ma Rainey's Black Bottom, White Tiger, Moxie, The Mitchells Vs The Machines

Going back a bit further:

Saint Maud, Color Out Of Space, Once Upon A Time... In Hollywood, Midsommar, The Lighthouse, Crawl, The Personal History Of David Copperfield

I highly recommend the In/Frame/Out YouTube channel for dissections of good indie and older classic movies. His year-end lists are always satisfying. The Scottish accent is the cherry on top.
