Bitcoin can't be used for that for example, takes many minutes, and costs a lot, so you would be standing in the shop for many minutes waiting for confirmation, but ETH can be, it used to be not available too because it would be too expensive, but now it's cheap and fast, so you pay and leave and all it takes is thirty seconds.
Fees fluctuate according to on-chain network activity. ETH is cheap now because the network is not as congested as before. Things have calmed down a bit, as the hype moved into other chains such as Solana and TON. Once ETH becomes viral again, fees will rise all the way to the moon. Luckily for us, ETH developers are working on a long-term solution to scale the Blockchain. Upgrades such as ProtoDanksharding and Danksharding will make ETH great again. Just like in the early days (low fees, fast confirmation times).
Who needs to switch to a L2 network or an altcoin, when you can have everything in one place at a low cost? If ETH does things right, it will remain the second-largest crypto by market cap forever. I'd keep this coin in my portfolio for long-term profits. Just keep buying, and "hodling", and forget about the rest.
If the sol and the likes of it won't move and innovate faster, in fact..
