The best entry point is Resident Evil 2 (2019), then play in sequence. RE1 introduces some characters and concepts, but they get better introductions in subsequent titles, and the game is… best experienced as a written summary, or while high.

You can also start with RE 7 if you want less action and more horror, it only intersects with the main storyline at literally the last moment, then move on to RE 8 before going back to 2.
