Re: Ideal 4x Travel
The downside of "open travel" (GalCiv, Imperium Galactica, etc) is not just the difficulty of defense but how it encourages the use of "stacks'o'doom" (where an attacker piles every ship they have into a single massive fleet, capable of destroying anything else). GalCiv imposes (artificially low) fleet limits to counter this strategy but that has other downsides.
"Limited travel" systems (with warp points, warp lanes or MOO2's "committed movement" system where a fleet cannot be recalled until it has reached its destination) make the "doom stack" approach less effective since it is less able to arbitrarily switch targets, making it easier to counter.
A hybrid setup (where warp points could be used for fast but limited travel, normal space for slower, open travel) would be the most plausible system but I have only seen this implemented in the play-by-mail game Spiral Arm - here systems are connected by hyperspace portals but you can also move one fleet via "deep space movement" to any other system, albeit more slowly. This gives defensible chokepoints but also the possibility of surprise attacks on inner systems.
Warp point creation in SEV offers the option of surprise also but it is too easily countered (System Gravitational Shielding).
