It might be easier to use something like xpytile within XFCE to handle the keyboard handling. Read about it here: https://github.com/jaywilkas/xpytile

like shinglify or xpytile.

You can request the feature at xfce's gitlab, or write your own script to handle windows however you want. Here are some pre-existing scripts you can try or use for inspiration: x-tile, xpytile.

Without too much disruption to your install, you could try xpytile https://github.com/jaywilkas/xpytile/ within your current DE for a few weeks to see if it works, sort of as a transition if you decide to move forward.

You may also want to try xpytile https://github.com/jaywilkas/xpytile/ or zentile https://github.com/blrsn/zentile

As an alternative tiling helper for XFCE I would suggest xpytile.

Perhaps not the most straightforward solution, but you could use a tiling helper script which is able to 'tile' windows maximized per default. For example xpytile https://github.com/jaywilkas/xpytile/ It's pretty OK. Only little problem is with xfce4-terminal which is tiled a few pixels too small, but that seems to be a problem of the terminal app.

If you want to have some tiling support but don't want to give up the comfort of a DE, like XFCE, you could try a tiling helper like xpytile.
