Do I need to worry about any of the following warnings?

Should be fine to ignore generally, but you need to review your output.

I've had some extracts from older pdfs that only has 􀀅􀀆􀀇􀀈􀀆􀀃, as clearly it was some unique font, that was not embedded with the pdf when created so it wasnt able to map the the chars. Where I have had some special chars like umalets "ä" in certain fonts its mostly seems to have come through ok, or has been extracted as "a" via the fallback fonts.

For the JPEG2000 error, im not sure as dont ingest any jpegs, but i assume in this case it hasnt processed this jpeg file at all.

Thanks for your response...I just ended up going back to using the fscrawler docker container since I believe its already preconfigured with tessearact and probably good enough for what I am doing..
