Old models Switches can be jailbroken without hardware modification, but the exploits were removed ( and now you need to do a hardware mod to jailbreak recent models ).
It's possible the Switch2 will also require a hardware modification.
The handheld 3DS consoles can be jailbroken by following a tutorial that holds your hand from start to finish. All you need is an SD / microSD card and a PC with an adapter to prepare the SD card.
( And to make modding a 3DS worth anything, you need an SD card anyway to store games. )
Jailbreaking Nintendo consoles is the goal.

Whats the point of jailbreaking a console exactly? Are you able to get free games out of? Or is it more about installing 3rd party software and such.
You can...
costumize the menu / interface in ways the company didn't implement themselves,
remove region lock to play games from outside your console're region ( and play the fan-translated patched version ).
play games without licenced cartridges ( either your own dumped games from your microSD card, or pirated versions ),
install mods / ROMhacks for your games ( legal but Nintendo dosen't want you to ),
install emulators with games not officially supported,
and as you said, 3rd party software.
On a jailbroken Switch, you can boot into the Atmosphere interface and do pretty-much whatever a non-jailed handheld console would do.
In the case of the 3DS, it means restoring online functions that Nintendo terminated ( though fan-made Pretendo ),
install costum themes and badges for the menu ( with Anemone and Theme Plaza ),
make a copy of your save files and then restore that save point ( Checkpoint ).
make StreetPass functions and MiiPlaza actually usable with Netpass
Install the 3DS port of the SNES9X emulator and play whatever SNES game you want ( or other emulators ).
If your volume button is broken, you can use the Rosalina menu to override the physical slider and adjust volume in software.
There is also a fan-run platform hosting the entire 3DS games catalog for free ( Nintendo no longer sell them ).
It's the only way to get 3DS eShop exclusives since Nintendo pulled the plug.
Thanks! Good to know!
