Questions about Samsung Galaxy Tab S7

Is there already a protective film for the Tab S7 that imitates the structure of paper for writing notes and drawing (paperlike screen protector)?

Hi, quick question, does the Galaxy Tab S7 have a nano SIM card slot option like the Galaxy Tab A7?

Is there a docking station with HDMI output to connect the tablet to a projector?

Is it possible to connect an external Keyboard and mouse (bluetooth) to the Tab S7? For example the Logitech k780 and the M590 ?

Maybe it's a stupid question, but I can't figure it out somehow. I would like to get the S7...now my question...is the pen already included?

All my headphones have a 3.5 jack. Can I continue to use them here with a USB-C to 3.5 jack adapter? The opinions on Google are divided. Has anyone here successfully tried such a solution? If so, with which adapter?

Is this an import? Is the device eligible to participate in the current Back To School campaign? https://www.samsung.com/ch/offer/tablet/galaxy-tab-s7-promotion/

Can the Tab be connected to an HDMI screen or projector via a USB C cable? Samsung DeX connection cable available.
