I'm unsure about Seraphis+Jamtis since I haven't been following it closely for the past few months, but this is what I do know.
tx_extra was a way to exchange needed miscellaneous transaction information, from the sender to the receiver. From what key was this received? What subaddress? Is there a payment ID? etc. Since ringCT is not a modular protocol, the solution was just to have a free field in the transaction for this information.
But with Seraphis this need shouldn't be present as every little information is part of a modular protocol and thus has its very own field, no need for a free-form field to dump the extra. So that is one potential anonymity puddle gone.
I'm unsure if this is going into production, but I know discretized fees have been tested and found working. This has been discussed all the way back in 2019 on the Monero Konferenco (https://youtu.be/XIrqyxU3k5Q).). Monero already employs a fee selection algorithm that has certain priorities that I'm sure anyone who used Monero knows about. Those cause the are the main streaks in picrel. But you can see that there are little dots and lines, and deviations and you can actually use these to trace Monero to a limited extent. For example, if you have a wallet that makes transactions at a static fee of 0.013371336 because you are an elite hacker who has his own wallet. You will show up as singular dots on the graph, and the rings are going to present a link between them. Making the fees more discrete numbers (powers of two to be exact, just lower the number of bits that can be used). You essentially force a lower resolution in picrel making anomalies (whether intentional or not) more or less impossible.
As for miners, I'm unsure if solutions exist. But they aren't a even a problem by now. This also has been discussed in a conference previously (the title was something like "you are not the money printer") and the conclusion was that adoption will eventually cover up miner TXOs.
