It's a huge piece for sure, but not the only one. For example, Firefox and Windows both don't support it out of the box currently. Firefox requires nightly or an extension, and on Windows you need to download support from the Microsoft store.

To be really fair, on Windows:
- H.264 is the only guaranteed (modern-ish) video codec (HEVC, VP9, AV1 is not built-in unless the device manufacturer bothered to do it)
- JPEG, GIF, and PNG are the only guaranteed (widely-used) image codecs (HEIF, AVIF, and JXL is also not built-in)
- MP3 and AAC are the only guaranteed (modern-ish) audio codecs (Opus is another module)
... and all of them are widely used when Windows 7 was released (before the modern codecs) so probably modules are now the modern Windows Method™ for codecs.
Note on pre-8 HEVC support: the codec (when not on VLC or other software bundling their own codecs) is often on that CyberLink Bluray player, not a built-in one.
Brotli? Is it still relevant now that we have Zstandard?
Zstandard is much faster in just about every benchmark, sometimes Brotli has a small edge when it comes to compression ratio, but if you go for compression ratio over speed, LZMA2 beats them both.
Both Zstandard (zstd) and LZMA2 (xz) are widely supported, I think better supported than Brotli outside of HTTP.
A large and important piece, but not the final. If it will remain web-only codec, that is no Android and iOS support for taking photos in JPEG XL, then the web media will still be dominated with JPEGs.

Would PDF 2.0 (which also depends JPEG XL and Brotli) put pressure on Firefox and Windows to add more easy to use support?

I don't think so: JPEG 2000, as far as I know, isn't generally supported for web use in web browsers, but it is supported in PDF.
