The YouTube codec selection is controlled by the upload resolution, the uploader's identity, and the view count / view rate.
Upon upload:- At 1080p and below, uploads will be in AVC only.
- At 1440p and up, YouTube encodes a VP9 version for all available resolutions. AVC encodes do not go above 1080p.
- At 8k upload resolution, YouTube encodes an AV1 version for all available resolutions. VP9 encodes do not go above 4k.

It also can load the system ffmpeg by loading it dynamically at runtime using dlopen (this used to be necessary for VAAPI but I'm not sure if that's needed anymore, it might work with ffvpx)

A Firefox/Chrome extension that blocks video and audio codecs you have chosen on YouTube - alextrv/enhanced-h264ify
For AV1 block. VP9 is possible accelerate by my old GPU.
VAAPI It is possible that you will update the software in your Linux, so new codecs of acceleration in Vainfo will appear maybe.
Firefox about:support is saying:
Code:Codec Support Information Codec Name Software Decoding Hardware Decoding H264 Supported Supported VP9 Supported Supported VP8 Supported Unsupported AV1 Supported Unsupported HEVC Unsupported Unsupported Theora Supported Unsupported
