Keep in mind the dual-core 11xx chips are a bit harder to boot than the rest of the line - but you probably need the power domain flexibility for most FPGA projects (1064 has way fewer practically-usable 1v8 banks.)

I've been able to use every bit of hard IP and high-assurance boot from registers using no vendor code whatsoever.

Here's what you are looking for:

The IMXRT1064 has a 4MB Winbond QSPI chip in-package, by the way!

The Xilinx FPGA that is sitting next to your MCU incurs multiple orders of magnitude more PCB-complexity than a little QSPI flash, haha.
