OK - a bit of education first.

Sump pumps are to capture and get rid of groundwater seepage, not sewage, so a sump pump would do nothing for your problem.

There are floor drains with a "check valve" - rarely are water tight due to floor grit getting in them and corrosion of the cast iron drain. Also, even if a floor drain with a backflow preventer on it stopped backed up sewage from coming out of the floor drain, that is a symptom, not the problem. The water/sewage would just back up till it came out at the next lowest drain - a basement toilet or sink, laundry tub, etc - or if none of them, then a first floor bathroom or sink.

The reason it backed up is your sewer pipes are partially plugged, or if you are on a septic tank and leach field, perhaps your septic tank needs emptying - about every 3-5 years for a normal size family. I presume your drains are generally working when you use a sink, flush, etc. - if not, you would have called a plumber by now. If it only backs up when large water flows are going down the drains (tub emptying, clothes washer emptying) then it is partially plugged, causing water to back up in the sewer until it comes out at the lowest point it can access - the basement floor drain, in your case. This will get progressively worse as time goes on, until a shower running will do it, then dishwasher emptying or kitchen sink emptying, till eventually even just washing hands would cause overflow from the floor drain as the blockage gets worse and worse. Or, it could totally block off at any time, dumping ALL drainage out the floor drain.

It is likely you only need your sewer line routed out from the house (they remove a toilet to gain access, or you may have a cleanout plug in exposed sewer piping) all the way to the street. Typically this should be done every 10 years or so. You do not want just an auger snake - you want a full scraper-type sewer cleaner, which will do more than just open a hole through the blockage - it scrapes the inside walls of the pipe, and will also cut through all but the lalrgest roots if thast is causing your problem. Call a sewer and drain contractor - plumbers rarely have these larger machines, which are capable of doing 100 or more feet of pipe to clean it all the way to the street.

It is likely that grease (the worst culprit), toilet paper, etc has built up in your pipes and reduced the internal diameter, restricting flow. A rooting will scrape this off and wash it away. In the process, the operator will be able to feel if there are any significant offsets or broken spots in the pipe. If so, then if you have selected a contractor who also has (and brings with him) a color camera, he will be able to inspect the pipe for such damage right after cleaning, which could be so minor as to not be a problem, or could need immediate digging up and repair.

The overhead pipe only makes the inside plumbing easier to access in the future - your blockage, since it is backing up in the floor drain, is in the underground part of the piping, so overhead sewer pipe would not help any in this case unless it ran overhead all the way to the street - imagine how that would look, even if they allowed you to do it.

Here are a couple of other questions and answers on the issue of sewer cleaning and basement drains, for you to peruse:
