Do any of the Intel fabbed FPGAs have a free development IDE? Last I checked, it was limited to older Altera-era FPGAs. I know the pricepoint of the Intel fab FPGAs is outside of even my work projects, but I was surprised to see how few FPGA families were supported by Quartus free edition, and was wondering if I missed something obvious?

The Cyclone 10 GX line is the most advanced thing you can get for free, but it doesn't seem to have had much popular uptake anywhere (nearly no dev boards, etc.)

Intel recently announced their new "Sundance Mesa" series of FPGAs, which are Agilex, and designed as low-end replacements for Cyclone, etc. And they said that they'll be offering Quartus Pro free for Sundance Mesa devices. This really surprised me; generally speaking, in terms of software availability, Xilinx is much more approachable and there are plenty of high-end choices while using Vivado for free.

But beyond that: I just run Quartus in eval mode and rm -rf ~/.altera* once every 30 days and reset it. One of these days I'll get a license for my giant Stratix 10 board when my designs are more finished...

Nope. But you can run Quartus Prime Professional in 30-day eval mode, I just did this for a Xilinx / Altera comparison. [Xilinx is ahead for deep combinatorial logic, I think because of the 8-level carry lookahead in each CLB. Altera was fine for well pipelined code. 1 Xilinx DSP == 2 Altera DSPs. YMMV.].
