It's hard to keep going back and forth on YCombinator. I use Lemmy.world to post here: https://lemmy.world/post/6104468 https://lemmy.world/post/6104468 This is about a YouTube video that walks through a reference design for an STM32F1, a beginner friendly chip with very simple startup. You only need the 100nF capacitors as indicated in the reference documents, but the video also adds a Ferrite Bead + Pi filter (1uF + Ferrite + 1uF), which is considered a good practice to reduce noise... but likely is optional and not needed at a beginner level.
