How far and how high they can pump will vary, according to many factors. Hose diameter. Amount of solids in the water. Distance. Difference in elevation.
Flojet offers a good one designed for temporary connection.

It has a 50' horizontal pumping distance through a 3/4" hose, or can pump up to 20 feet straight up through the same diameter hose. But in simplest terms, for every 2 feet you go up, you lose 3 feet of distance— and that's distance
through the hose, not straight-line distance. Which means you could only pump 20 feet straight up through a 20-foot hose, but not through a 25-foot hose. Not that you
want to go 20 feet straight up, but you get my point. Us a hose that best fits the distance to be pumped, because the shorter the hose, the better for most efficient pumping.
Flow rate slows down the more you try to pump uphill, while at the same time the amperage draw goes up. If you're on a 20amp circuit, you've got full capabilities, but if you're only on a 15amp circuit, cut the maximum distance AND height in half.
If you go with a macerator pump, let me suggest this: Dump the black tank when it's only half full— but fill it the rest of the way with HOT water before dumping. That helps soften the solids to help the macerator pump grind better. And by all means use enzyme tank treatment to break down the solids as much as possible before pumping.
