Okay I already said this above but...
You should never delete individual images on the card via the camera as it can cause read table errors, yes the option is there but you should not use it!
You should never delete individual images on the card via a computer as it will absolutely guarantee read table errors and can also corrupt the card leaving it useless.
You should never format the card via a computer as it can cause read table errors and can also corrupt the card leaving it useless.
Inserting the card into other devices can also cause issues for example digital photo frames, games consoles, televisions etc. The way some devices access information on the card can cause read table problems, although this is rare.
Using a card that has previously been used in another branded camera can sometimes cause issues, the Nikon D750 for example was famous for this and would throw up all sorts of error messages if you were using a card that had been previously used in a different camera even when the card had been formatted before use.
You can either transfer photos from the card to your computer via usb or via a card reader, the card should only ever be formatted in the camera.
This is the case for all cameras not just Sony.
You do need to be more careful with cards in Sony cameras in regards to one aspect. When you format a card in most cameras it deletes the data from the read table, this means that the data itself is still there it is just the index that is deleted, the files eventually get written over. With Sony it doesn't, it actually does a low level format of the card. You will probably notice that formatting a card in a Sony camera takes longer than other brands, this is why. This means that with other brands if you accidentally format you can use software which will in most circumstances recover the files from the card if it hasn't been used since and the data has not been written over. With Sony this very rarely works and you will need a lab recovery and the success rate of recovery is very low.
