How much work it is for you depends on where you are in your career, especially what engineering you have access to and what tools you have unlocked. Apart from that it starts with choosing the right ship, and everyone will have a different opinion and build strategy for that

. You can get away with a number of ships, and there is certainly a matter of preference, but for me I'd say the best ship you can do it at the moment is the Krait MKII. Mamba is good to get through to the Titan relatively unharmed, but lacks the hardpoints to disturb the vents and do proper damage, I think. People do it in Anacondas, but they usually know how to deal with the interdictions in relatively slow ships. I guess the cutter will work well as it can be armored to hell and back and still be fast. My preference, as said, is the Krait.
Getting to the Titan has a few prerequisites. You must have the Thargoid Pulse Neutralizer to get through to the Titan, and you need to get through the toxic Maelstrom cloud and survive it. The pulse neutralizer can be bought for materials (not credits) from the tech brokers on the rescue ships. You cannot get through to the Titan without it unless you manage to piggy back on another CMDR's back, but you have to stay pretty close for that to work.
To survive the toxic cloud you probably need the caustic sink launcher. It's also available from the tech brokers on rescue ships, but it's a one time unlock for materials, and then you buy as many as you need for credits. I'm not sure you can make it through the cloud without it. In theory you can constantly burn off the caustic, but your ship will probably a wreck when you arrive at the Titan. You can also try to battle the caustic with decon limpets. The Titan environment itself is not toxic.
To keep the ship cool you have three things you can work on: Have a cold running ship to begin with, bring ample heat sinks, or bring a thermal vent beam to cool off on the Titan's surface.
As an example,
this is my AX Krait I modified for the current Titan runs. It's usually a normal repair build to fight Thargoids, I swapped out some weaponry and utilities to match the need for the Titan runs. The empty hardpoint is where I have the nanite torpedo pylon (it's not on ETSY yet). It deals very well with most interdictions (I struggle a bit with Basilisks but still get away in the end), and it deals well with Glaives if need be. It gets through the cloud relatively quickly; I need to eject the caustic sinks twice until I arrive at the Titan. The slower your ship, the more caustic sinks or decon limpets you will need.
