About the formats
.webm
WebM is an open video format designed for the web, usually with VP9 or AV1 video. Browsers play it well, but iPhones, video editors and many TVs don't.
.m4a
M4A is audio stored in an MP4 container, usually AAC. It's what iPhone voice memos, iTunes purchases and many recorders produce.
