If you go 11 speed wheels, they may have an 11 to 10 speed spacer like my RS81 shimano wheels did. Check with on one. You can then use 10 to 8 speed cassettes on the wheels. If you buy 11 speed, you can upgrade to 11 in the future, without issues.
Your 9 speed cassette will just go on a 10 speed freehub With a 10 /11 speed you’ll need a spacer. The AL30 Wheels are not very good BTW the freehubs are rubbish and break easily and the bearing last months not years.
