Here are the options I know about.

1) NTFS  with FUSE on both sides
2) ext with Paragon’s commercial ext driver for macos (FUSE ext options don’t look great).
3) FAT32 or exFAT
4) ZFS

I haven’t used the paragon ext driver.  If it works well it is likely the best option.  

NTFS will probably work OK.

If you do FAT32 note that with a larger cluster size you can have semi-reasonable sized partitiions, 32GB I think.    The defaults, which windows will give you,  give a max 2GB I think.

zfsonlinux works well in my limited experience.  

I can’t speak to the stability of the mac ZFS options. This one looks reasonable: http://open-zfs.org/wiki/OpenZFSOnOSX

Alternatively, put everything on linux, have linux dual-boot on bare hardware and as a VM on MacOS.  
Have linux share out its native home partition via NFS.  Not sure how reasonable this is - e.g., can you 
get a VM running pre-login? 

Warning, macos filesystems are case-insensitive by default.  I had trouble when i 
formatted an HFS+ filesystem as case-sensitive, some software just broke.  So NTFS might
be a better fit.
