Sudoku by Thomas Snyder

[This puzzle comes from the 2022 US Sudoku Grand Prix round. This puzzle is the first of three classic Sudoku that did not have a visual theme, however (spoiler for hidden theme and solving path) the digit eight is still a key part of the theme, one of a pair of digits that sets up a lot of pointing pairs in the grid at the start. You can get the center number — an eight — by following just the one number through four symmetric pointing pairs.]
