I recently started a car after it sat for about 5 yrs.
I sprayed "fogging" oil in all the cylinders. It sticks to the walls of the cylinders to provide lubrication.
Cleaned plugs, checked leads, replaced distributor cap rotor, removed injectors, ultrasonic cleaned them and replaced o-rings. Checked fuel pressure regulator.
Just prior to first start. Checked oil, it was "ok"(colour wise) . Drained some maybe 2 litres poured it back in the top. Spayed more fogging oil. disconected spark plug leads. Turned the motor over a couple of times just to get oil flow and pressure. Replaced plug leads. Started, warmed it up. Did oil change including new filter. In your case, 10yrs standing, I would do an oil and filter change(cheap oil) run for a little bit and then drain and change oil again(good oil) .
As stated above fuel pumps might need attention. In my case it was a no start but before I had to pull pumps, I replaced fuel pump relay. Then it started.
My ignition amplifier died during lay up
Over $200 bosch unit relatively new before lay up, maybe 2yrs. You can find cheaper at Repco.
Also things like, rusted discs, degraded brake pads, WATER PUMP FOR WIND SCREEN( I had 2 for the wagon) . The wind screen pumps can be taken apart, lubricated and freed of rust and crusty build up very easily.
I replaced all the engine belts and front engine seals. I should get a belt tensoiner soon, mine was ok.
I suspect the engine hushers have dedraded from not having oil. My engine has a tiny bit of noise.
I also took the opportunity to install new parts that I bought over the years as spares. I now use the date of rego as my "day zero" as a reference for when I will need to do preventative maintenance.
I am about to do a full brake fluid drain and replacement.
Many of the rubber parts need to be in movement and lubrication some what regularly to avoid their cracking.
Ten years is a long lay up. Your suspension may need attention also but the end result should bring satifaction as my build has done.
Lots of really great advice from guys a lot more wiser and experienced than me here. We have a great parts network. They helped me enormously. Welcome to Ozvolvo. you won't regret it.
