First of all, avoid the term "senior dev". That means 5 to 7 years of experience. You're way past that.
Next: Web programming is something junior devs can do. (Maybe not as well, but they can do it, and for less money.) You need to move on to harder things, where your experience is worth more money.
What harder things? You mentioned SQL Server. You say it's "losing relevance with the ORMs/EFs of the world", but there's more to the world than that, and I strongly doubt SQL Server is going away. Find places where it is in use, and go there.
Alternately, you can try to move up to architect of someplace with a big web presence, but I'm less clear on how you make that shift.
