55 million light years is about correct. Wikipedia still has 53.5 ± 1.63 Mly from older observations, but appendix I in paper https://iopscience.iop.org/article/10.3847/2041-8213/ab1141 has a bit more on the distance measurements they used. They arrive at 16.76 ± 0.75 Mpc, which translates into 54.7 ± 2.4 Mly.
On the other hand, the jet from the M87 black hole is quite large and we have good images of it. It's even resolvable by amateurs, I hope to take a picture of it over Easter with a small telescope.
