I would say there is nothing to plan ..
.. if Max offers several bitrates for 1080p, they will also be available in SF.
But in most cases there is only one for H264 (avc) and one for H265 (hvc)
Example The Head.s03e01 => here
I can select different bitrates with yt-dlp - but I always get the same size ..
.. these are just different parts for possible ads
