Ubuntu recommends /, /home and swap [1]. Fedora recommends /, /boot
and swap [2]. OpenSUSE has several sets, but the "simple" and "dual
booting" recommends /, /boot, /home and swap [3]. Debian says [4]:

"For new users, personal Debian boxes, home systems, and other
single-user setups, a single / partition (plus swap) is probably the
easiest, simplest way to go. However, this might not be such a good
idea when you have lots of disk capacity, e.g., 20GB or so. Ext2
partitions tend to perform poorly on file system integrity checking
when they are larger than 6GB or so.

For multi-user systems or systems with lots of disk, it's best to put
/usr, /var, /tmp, and /home each on their own partitions separate from
the / partition."

Interestingly, the Gentoo handbook [5] recommends /, /boot and swap.
Damn, I haven't installed Gentoo in a long time, I hadn't looked at
the handbook in years.

Anyway, Debian is the only "big" distro recommending separated /usr,
and then only for multiuser setups. It's really years since I've
looked at the recommended partition schemes: when I started using
Linux, a separated /home was almost a must. And we had tiny hard
drives then. Now get out of my lawn.
