Steel, wood or aluminum

First of all, thanks for letting me join. I am a member of the Trawlerforum and another member in that forum suggested I ask my question as well on this forum, where there are apparently more owners of boats made out of steel, wood or aluminum

Currently I have a Defever 49, we sail in the Med and I am looking for a larger boat (up to 70'). I would like to have a boat that can cruise at around 9 - 10 kts and go even faster if possible, so that we can outrun extreme weather when it shows up. With our Defever we cannot do that, 7 kts is about the max we will get.
Also we would like to have more space onboard, we more or less live on our boat, so we can use extra storage space, but also extra space for guests.

I am searching online for boats and I have found a couple of boats that might be interesting, however I am not familiar with the pros and cons of the different hull constructions. One boat is made of steel, one is made of wood and the third one is aluminum.
They are all older boats, 1990, 1997 and 2001 and I know steel does rust, aluminum apparently can just desintegrate and wood I have absolutely no clue about. I have not yet seen the boat, so I don't know if it is wood with epoxy on top of it or if it is painted bare wood.
Some people have already told me to stay away from wood, but others said it should not be a problem if taken well care of.

If any of you owns an older steel, aluminum or wooden boat, I would gladly like to hear your insights, the problems you encounter, if it is very maintenance intensive (more than GRP), any tricks to find out if the boat is in good condition etc.

Appreciate your insights
