I had a user witness me using my Samsung Tablet in Dex Mode (which allows for an extended external monitor, keyboard, mouse, etc) and running in desktop mode. The inevitable question of "how do I do that?" followed. Before I tell them that they need a Samsung device to do this, I figured I'd ask, did Apple ever actually catch up with this?
iPad 2, iOS 9
Most iPad models support AirPlay - and/or connection to a single external monitor using an appropriate HDMI Adapter. The most recent models of iPad Pro also support HDMI Alternate Mode/DisplayPort connections over USB-C. Compatible iPad models can be connected to a single monitor/TV.
You should note, however, that iPad does not support an extended-desktop view - but instead permits the iPad display to be “mirrored” to a compatible external monitor/TV, preserving the iPad’s screen aspect-ratio. The iPad can also “stream” media content directly to an attached monitor.

You can use 1 external monitor with the iPad (mirrored). Its been an option since 2011 or so if I recall correctly.
You can use a keyboard since the first iPad in 2010.
You can use a mouse since 2019.
There is no specific desktop mode for iPad, it continues to use the regular iOS version however.
