Did you try flatseal for Wireshark? It abstracts the process of messing with permissions.

That being said, unless the flatpak has some features your distro version doesn't, for trusted software package is always preferred.

Flatpak is really for untrusted software/proprietary and projects that update with new features often.

You misunderstand, Flatpak has no mechanism whereby the appropriate permission can be granted. At all.
