Please consider adding H.265/AV1 encoding/decoding benchmarks. I know GB is strictly closed source but I guess you can license these libraries. One caveat though: some of these encoders/decoders are not optimized for many-core CPUs.
Please specify the exact version of the OS the test is running on. E.g. unpatched Windows and Windows with all HW vulnerabilities mitigations applied may show very different results.
For Linux that means showing the exact kernel version, e.g. uname -rand parsing the command line for the mitigation parameter, e.g.
cat /proc/cmdline | grep mitigations or grep . -r /sys/devices/system/cpu/vulnerabilities (don't know which one is easier to code for).
Please, please, please compile all the binaries using the same compiler. Clang 8.0 supports pretty much everything under the Sun nowadays. GB4 shows very different results for different OSes on the same PC: Linux vs Windows GB4
Newer CPUs have instruction sets (e.g. AVX/AVX2) to accelerate certain workloads. Looks like you don't have any tests for that.
Nice to have:
It would be great to have stress results (not included in the final scores), e.g. run a certain test for over 10 minutes and show its performance for the time span from 1 to 9 minutes (e.g. exclude the first and the last minutes).

I've read your tech documentation and it looks like you use LZMA only for compressing text. I guess text is a very specific use case for compression and it make sense to compress other data types, e.g. executables, HTML, images (BMP), audio (WAV), PDFs. A lot of other popular modern file formats are already compressed, so it doesn't make a lot of sense trying to compress them (docx/xlsx = zip, most audio/video codecs are already highly compressed, etc.)
I purchased a Geekbench 4 license a while ago but seems isn't valid for Geekbench 5 beta.. will Geekbench 5 require purchasing new licenses? can purchase any license now? any discount for Geekbench 4 owners?
finally any news on Android and IOS Geekbench 5 beta?
