Fedora :: F11 - How To Reduce Inode Usage

I am running into a scenario where inode utilization (df -i)on a partition is 100% I want know

1) Is there a better way to list the total count of all files in a partition and just display total number of files in each directory in that partition I can get approx total for the entire partition by following commands

ls -Rla | wc -l
find -type f | wc -l

whereas ls -Rla gives too lengthy outptut with all the files in each directory

2) How to know inode utilization for each user or system account? There is huge number of files and how to remove it
