I'm working on the most recent book of Dan Willis' Arcane Casebook series. I stumbled onto them and got hooked.
The series is noir detective set in the 30's, but with magic. As specific as that niche is, it has been done before, but these have been well worth reading. The way magic works is well-defined and has a lot of built-in limits. That keeps it from overshadowing the detective stories that are at the heart of the books.
These also do a good job of acknowledging the common tropes of the genre, without accepting them as limitations. For instance, cops don't generally like private detectives, but the specific relationships between cops and detectives are varied and interesting.
The worldbuilding often goes in unexpected directions. The implications of magic affect everything. A lot of the world looks very familiar, but there are some prominent differences between our world and theirs. It's a fun place to learn about.
