What if the size limit of the next block would go up if the average transaction fee goes up but down if the amount of transactions goes up. If a miner would try to play the system by filling his block with fake transactions then he would have to mine 2 blocks for the price of one which wouldn't be profitable.

Filling your own block with transactions costs nothing because you are getting the fees of all those transactions in the coinbase transaction of the block they mine (it is like putting money from left pocket into the right one). Not to mention that such an attack could be a collaboration between more than one big miner where they both spam the network to inflate the fees.

I can't understand why we would keep the block size limit to 1MB just to reduce the amount of spams because at the same time we would make the network less efficient for peak periods (huge trade off). Someone will have to come up with a viable solution at some point...

Block size hasn't been 1MB for nearly 4 years now. The block weight has been 4 MB which has translated into average size of about 1.5 MB.
This "cap" is not there to reduce spam, it is there to prevent spam attacks that would cost nothing to perform.
We also don't want to just bump the raw size, we aim to increase the capacity without doing that. For example Schnorr signatures already get rid of some of the useless bytes that for years we've put into each signature. There is also aggregate signature that can reduce the size of transactions with more than one key.

LTC can move large sums safely and as a bonus cheaper then Btc.
Doge can move small and medium sums faster and cheaper and safely.

That's because they are not used. It is like saying I can speed in this street that nobody else is in but I have to be stuck in traffic in the other street that is the exact copy of this one but it is used by a lot of cars.

Tether is being used to move wealth quickly and so far safely.

Tether is neither quick nor safe. It is a centralized altcoin that is extremely risky to use because it could be shut down at any moment very easily.
If you are happy with centralized tokens pegged to fiat then you can use PayPal. It gives you a token that is also called USD which is pegged with dollar and is fully centralized, fast and as safe as it gets.
