5.19 release notes list 100's of bug fixes:
https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.19 .

According to https://www.makeuseof.com/linux-kernel-5-19-released-new-features/,
there are at least 7 items of interest:

   * ARM-Related Performance Boosts
   * Intel Overheating and Battery Drain Fixes
   * LoongArch CPU Architecture Support
   * Graphical Improvements
   * Numerous Networking Additions
   * Newly-Enabled Accessories
   * Better Compression

It's been my experience, new laptops and desktops need the newer
(newest?) kernels because sound never seems to work with an older
kernel.

You can install the 5.19 kernel using metapackages:

   * linux-headers-generic-hwe-20.04, linux-image-generic-hwe-20.04
Or
   * linux-headers-generic-hwe-22.04, linux-image-generic-hwe-22.04
