Like what is the ultimate fate of the voyager probes and others on escape trajectories? My understanding is that space is far too sparse for these things to ever hit anything by coincidence, so their eventual fate is probably to be ejected out of the galaxy at some point.

They are then unlikely to be moving fast enough to actually cross intergalactic distances quickly enough for the expansion of space to not outpace the distance covered, leaving them in this void forever.

How long would they be recognizable as technological objects before the eons worth of stray hydrogen atoms erode everything away?

Best way to leave the milky way is probably to slingshot around a black hole. Stars get ejected from galaxies all the time like this

You don't have to be Ben Browder and surrounded by muppets, but it helps
