MS Office 4.2.1 and Claris/AppleWorks 5.0.3 were the last to work on 68k. Both work on a 68030 or higher, and need 8MB (for Office) and 12MB (for Works) RAM.

They were both good for their time. Not really sure which one I'd go for.

I suppose it depends on what office package you currently use. MS Office might have better compatibility with modern office packages than ClarisWorks.

There may be other packages, but there were the two I used.
