I was going to link to each track separately under descriptive headings but it seems that isn't possible, so here they are arranged by album (if one of the tracks doesn't appear on the album page try clicking on the "Next 10 Results" link). I took your thoughts into account (you wanted something that wouldn't sound out of place in an Indiana Jones or swashbuckling movie), although I also included some other action pieces that might be suitable.
Apologies if it seems that I haven't been very selective - I know this is a huge list. I mostly chose these directly from my search results, so I haven't scoured every single album on the site, hence I might have missed some other good ones.
I've included some of my thoughts on how each track might be used (e.g. briefing, in-game combat/action or ambient, title/mainhall music, cutscene/cinematic etc). Feel free to decide how they could be utilized.
Action And Adventure Vol. 1Strike Eagle - In-game action. Would fit in with the other tracks more if it weren't for the rock/electronic parts and the drum beat, so I’m not sure about this one.
Tank Battle - Briefing / in-game action.
Action And Adventure Vol. 2The Polis – Briefing or in-game; has parts that might suit ambient and action segments.
World Wonder – Briefing, or in-game ambient.
Action And Adventure Vol. 3Sails Under Strain – Sort of patriotic, emotive sounding. Could be used for a cutscene, like for a ship leaving dock for its maiden voyage.
To the Sea – Very similar in feel to the above track.
Action And Adventure Vol. 4Guns And Powder – Short in-game pirate-like theme.
Action And Adventure Vol. 5Glory Underway - Might be good as a title track, or for use during a command briefing/cutscene. Has a slight sea-going/pirate-like theme to it.
On Another Episode - In-game action.
Out of Time – Slow paced, sad emotive music. Might suit a cutscene.
Soldiers and Pilgrims – Grand/heroic, cinematic memorial theme. Possible victory music.
Action And Adventure Vol. 6Bomb Launcher – In-game action. Has guitars and synths, so it might not fit with most of the others. Sounds really good though.
Missiles – Dramatic in-game action. Sounds a lot like Bomb Launcher, but slightly less heavy with the guitar perhaps.
Starships - Orchestral with synth elements. In-game action.
Action And Adventure Vol. 8Collateral Damage – Cinematic battle, or in-game action.
Cruel Spring Ahead - Tense sounding track. Could be suitable for briefings as well as use in-mission.

Battle Themes Vol. 2Foreign Shores – Tense sounding, in-game ambient.

AudionautixThe following are from Jason Shaw’s Audionautix site (
http://www.audionautix.com).
Track #53: Big Intro - Short in-mission event music for appearance of new friendly units or something.
Track #54: Big Intro #2 - As above.
Track #64: Enemy Ships - Event music for when enemy units appear.

After listening to some Elgar and Hendel, I'm thinking that some other classical pieces could be included depending on where the missions take place, just to get across a pan-European (or wherever) feel into the mod.
EDIT: Deleted duplicate track under wrong album title.
