Transaction fee are not usually predictable or static but when there are higher transaction in the blockchain and there are no enough miners then you would automatically see the transaction fee are getting higher because there are lesser miners, but when there are lot of miners then you would see that the fee will remain the way it's or a bit lesser (depends). Most times higher demand of transaction could triggered the fee to increase unexpectedly but if we know that there are lot of miners then there is no need to worry about the market because transaction fee would be far way more cheaper.
I think you’re wrong about this, more miners doesn’t really cause the fee to stay low or less miners means it stays high, the real problem that affects it staying low or a high is the congestion on the network. During the last saga where transaction fees sky rocketed it was due to the presence of all this Ordinals and inscriptions which were actually causing congestion and at the same time over paying for their transactions to get confirmed coupled with the actual bitcoin transactions it caused lots of congestion then and it is congestion that actually leads to high transaction fees because that what most nodes prioritizes.
Right now if you even check some of the bitcoin block explorers you will find out that most of the blocks aren’t even filled completely with transactions signaling the fact that the network is very well less congested and the reason why the fees have stayed so low. Also this is the period where most people are holders because they are anticipating more bitcoin pumps and there for you hardly see transactions on the chain. During period of sale offs you will notice the movement of coins to and fro exchanges their increasing the congestion on the network.
Personally I will say as long as there is no coming back of those junks then we can say there is high probability of it staying not highly congested
