Hello
I intend to sweep funds from a paper-wallet and other funds from an old BRD-wallet (12 words known) into Electrum (preinstalled on Tails).
Nothing to worry about, you simply just import the wallet seed phrase into an electrum wallet and choose the Bip39 option. BRD wallet supports native and nested SegWit address so when choosing the script type make sure you know the address script type to use. Here is a
thread by Fillippone to guide you
For security purposes you can as well create a new electrum wallet and seed funds from there to there.
You can send bitcoin to any type of its address formats from any type of format. It’s not necessary they must be in same script format. So pick any of the first two from the site.

Sometimes in the future I will be required to show simple Bitcoin tasks to an audience. That means a transaction (of about 5 USD) to a
person of the audience should be confirmed withhin about 5-10 minutes. Should i use Bech32m (Taproot) addresses for such a demo?
The problem with bitcoin transaction is you can’t set a time limit for it. The default time for a new block to mine is 10 minute if you pick the high priority fees but still this time varies as it can be way less than 10 minutes or higher than it.
