With all these characteristics, Electrum fit to be the best wallet, while Bitcoin Core is the best for privacy but being a full client wallet. For multi-currency, most are close source, but very important to go for open source noncustodial ones also.
You made newbies fear of bitcoin and bitcoin wallet when you shown your knowledge and get them lost with many features and many things to consider for a wallet.
Wasabi is the third that comes to my mind, but due to some certain reasons, I can not recommend Wasabi for newbies. Even for privacy, it should be one of the most recommended wallets as it coinjoin multiple transactions and make tracking difficult and nearly impossible, but there are cases bitcoin users will send money to exchanges using Wasabi wallet and the bitcoin frozen by the exchange, experts are aware of these and the reason they make use of Wasabi successful without facing any problem. Due to this, I will suggest electrum, there are ways to make use of electrum with you still have high privacy, like the coin control, coin freezing and address freezing, but due to it connecting to central server decreases the privacy, but out of the SPV wallets, electrum is the bitcoin best but not disputing Wasabi offer most privacy, even than electrum.
Wasabi gives people more privacy with Coin Join transactions but this wallet is not hard to use. People can use Coin join or don't use it.
The restriction is the minimum of BTC to be queued for Coin Join. This min is about 0.1 BTC.
