Yes.
One SIM card, one contract, one bandwidth.
The iPhone “splits“ it into internal use and the hotspot feature for other devices.
But I don‘t know in which ratio/priority.
Yes.
One SIM card, one contract, one connection to the cell tower. The available bandwidth for the iPhone is shared between all devices.

But I don‘t know in which ratio/priority.
If you have a 2nd data-only SIM card (in a dedicated hotspot or the iPad) then you have 2 independent connections to the cell tower.
EDIT: updated
Also remember that your battery life will decrease faster because the hotspot makes your phone hotter.
Just a heads-up from personal experience, using the hotspot everyday it's something that I would not advise, you are going to repay the iPad monthly sim card with an early iPhone battery replacement.
Probably it's still convenient considering the price monthly of the plan + ipad cellular additional cost. If you can deal with your iPhone need of charge during the day.
Maybe it's not your use case, but I just wanted to share my experience
Confirm re iPhone battery. During COVID isolation I did not have that good Internet at home for the number of calls I had a day so I had to rely on my iPhone battery. Well now the phone is 2 years old and battery health is 89 %. Not the worst but I think it would have been better if I did not rely on it for hotspot at that period.Also remember that your battery life will decrease faster because the hotspot makes your phone hotter.

Yes you can do this with no problem. The iPhone will be the primary priority for internet traffic, I don't know the ratio of the breakdown. Depending on your carriers plan and restrictions your hot spot may have a gimped speeds and a data limit. Your phones battery will drain a bit faster due to it transferring larger data out through the WiFi, and someone else more technical would know better but iPhone uses bluetooth also for this hotspot connection.
This does not degrade your battery more than normal similar use. Just know you are using the phone more and using more of its processing power so usage is increased and heat is the byproduct.
On an everyday use depending on how you plan to roll with that set up, it may be more beneficial to have a separate data plan for the iPad. The also depends on your plan from the carrier, i.e data cap, throtling, slow hot spotting, and the likes.
I am really curious to what the priority ratio is now.
Bluetooth tethering has gone the way of the dodo. The only options for tethering now are wifi, or Lightning cable with a Mac. Personal hotspot uses Bluetooth to set it up, but it’s still wifi tethering.Depends on how you connect the iPad. You can manually set up bluetooth tethering.
