Archive This! has served me well for many many years. Alas, it's a shame to no longer be available for or compatible with contemporaneous versions of Thunderbird (e.g. 78+).

The replacement I found that worked similarly (and provided much sought-after relief) is the "Quick Folder Move" extension by Philipp Kewisch.
