Opening documents using File Explorer

You have several options going forward:
1. Use 3rd party apps that install on the user's computer (see post from Myles)
2. Use One Drive for Business client on the user's computer
(properly train your user community)
3. Use 3rd party SharePoint apps that run in the browser, e.g. https://www.slimapplications.com/wp-content/uploads/2020/12/ExplorerContextMenuJPG.png
4. Use GPO to map SharePoint network drive
(stability and handling authentication is often a problem)
5 Last and not least: train your users to use the web interface
This may not work well for some organisations with traditional employees but it may prove the best option in the long run.

Each option has it's pros and cons. Get clarity on the requirements and assess whether the users need versioning, metadata, ability to start workflows, search, check-in/check-out, need to handle technical formats (e.g. dwg), have local synched copies of documents, ...
and of course take into account costs because some of the solutions are licensed.
