Head pressure. It will affect the return pump that you will need but that is the obvious one and you knew that already. 
When I was in the planning stage for my basement sump I spoke with Chris from Reeflo he was instrumental in advising me on the correct piping to get the flow rates I wanted for the 210 upstairs. I was shocked the difference switching from 1" to 1.5" diameter makes in flow rates.

Use big plumbing. I used all 1.5" for the drains on my 150. The only thing I'd do differently is drop the siphon to 1". On the return side, I run 2" to my manifold (which I don't really use), then 1.5 to a wye that splits to two 1" return lines.
I would also plan on using an external return pump. There are some internal pumps that can do it, but there are many more external options and it is far easier to drill the sump before its all installed.

I use 1.5" going up and down. The Vectra L1 does a fine job. Flow rates are highly overrated. I get over 400gph with it turned up about half way. I also recommend a trap in your drain line upstairs, to help keep noise down.

I run a BeanAnimal drain and have zero drain noise. Read up on it a bit if you haven't already. The trap idea on an open channel drain isn't something I've heard of before on a tank, but I don't see a reason why it wouldn't work.

other then correct plumbing , Humidity, Heat and cooling..... If its in a open area in the Basement you might require bigger heaters and Maybe heating year round... Also humidity is a Big concern...... I have a window in my sump room with a fan on humidity controller. one fan can blow out one in to exchange outside are better... This is SUPER important if your HVAC unit is down there especially if its close to your sump ... ... Of course size of sump is relevant to rather there will be a issue or not
I Use 1-1/2 plumbing for supply lines and 2 inch drains from tank.. Running a REEF-FLO Hammerhead .. my return goes 12 inches above basement floor to floor joist that is 7 foot up.. it then goes over 8 feet and up another 6 feet to reach over top of tank.
ALSO . Remember you need a lot of extra capacity for drain back during power failure or pump off ... Do not use a check valve for this...
Good Luck ..

I initially made it this way thinking it would help keep siphon in the line on the left....but later realized it's really not needed because you only need a siphon ABOVE the valve. The center pipe here is a 1.5" emergency drain, and the one on the right is a secondary line. This setup works flawlessly. My radion fans, even on low, are louder than my drain. Here's a link to a video inside the overflow box: If you hear a tv, it's about 33 feet away.
