Thanks for your reply, Mladen.
In terms of OL8 improvements, that's good to know. As far as NVME goes,
I'm on AWS, and the newer nutro-based instance types do, in fact, use NVME,
so that's good for me.
Honestly, I really rarely have a chance to upgrade (we still have one
OEL5/11.2 DB system), so I wanted to try to get as up to date as possibe
with all this.

OL7 is also a long term release. It will be supported for the next 5 or
6 years, far longer than Oracle 19. OL 6.x is still around. I know of
quite a few Oracle 12.2 instances running on OL 6. I am even supporting
some of them. OL6 is running Linux kernel 3.1. OL 7 is running
relatively recent kernel 4.1. OL 8 is running kernel 5.4. Of course, I
am talking about the "unbreakable" UEK kernels. The main advantage of
Linux 5.x kernels is the new kernel lockdown mode. It's a security
feature, not a performance feature. You don't lose much. OL 8 is
remarkably similar to OL 7 if you disregard things like dnf instead of
yum and nmcli. The real improvement is the NVME driver which has
switched to polling over the interrupts but that only applies if you
have a NVME drive in your database server. Most DB servers that I know
of don't have a NVME drive which is a shame. NVME drives are really good
for redo logs. Unfortunately, they can't be shared, so no RAC.
