Be careful with the 223 and heavier bullets. This is an experts cartridge combo for somebody well versed in reloading and match shooting. It has been popular in F-Class in years past but most of us who used it dropped it after a while. It can be an extremely frustrating combo to get shooting right.
The 308 is probably your best choice. The 6.5 CM while being an excellent choice is limited in brass quality and is not well supported in the shooting community. If you want to shoot precision matches then the 308 is the universal choice while the 6.5 will put you into an open class where there aren't many competitors.
Look at the 260 Rem or 6.5 x 47 Lapua for choices other than the CM. Lapua makes brass for both.

Thank you Steve. 1 more for the 308.
Consider: if precision shooting with longer distances is the goal, start reloading now. Factory ammo just doesn't cut it
If you reload for precision shooting, the core tools and procedures are the same regardless of the chambering so your investment can span all the options you will want to try.
The odds of you staying with just one option for more then a season is highly unlikely.. Once you start and see all that is possible, it takes a strong resolve to not look over the next hill. So I wouldn't get caught up in trying to find your 1 true life mate.
Look at your goals and priorities for the next season. Work towards that. Then change as you see fit and as you are exposed to other options.
I have had the pleasure of shooting damn near everything considered accurate. Even designed my better mousetraps. I now spend most of my time on the 223 and 308. They work, simple to set up, lots of info out there.
For general plinking even to 1000yds (and beyond), the 223 is hard to beat. I would suggest bullet weights from 68gr to 80.5gr. All are easy to load and tune for. Use standard components and no more fussy then the match 308 ammo (or any other precision cartridge by the way) I make.
8 twist is ideal.
the 90gr VLD's offer wonderful ballistics but can be tricky to set up.. Not an option until you become a very experienced loader.
As for 1 rifle for two tasks... forget about it. First off, hunting rifles today are so inexpensive, why would you want to heave a big heavy pig of a rifle through the bush?
And Yes, most precision rifles are going to be heavy with stocks set up for position shooting and peak accuracy... not lugging quietly through the hills.
Enjoy your quest. There are as many options and opinions as there are shooters. Look at the cost of shooting and see if what you think you want, agrees with your wallet.
Add reloading into the mix asap.

Jerry, thank you. Seems like 308 would be a better option for me as I could make it a more viable round for deer hunting. From what I gather from your input, both calibers are workable rounds for plinking but I am by far an expert at hand loading. And, as you said, it all depends on the wallet. PS: I'll keep your website in mind if I need someone to prep a rifle for me. I gather you ship to Ottawa?
Unless you are going to play with very heavy .224 bullets, like 90gr VLDs, you don't need a 1:7 barrel. 1:8 may be optimal; 1:9 will do well with 69gr, perhaps some 75gr bullets. 69 and 75gr match grade ammunition can be purchased. Cheap 55gr ball is OK for casual shooting at shorter ranges.
There is excellent .308 precision ammunition available. Stuff like the Hornady 155gr match. It shoots very, very well in most all rifles.
However, if you are going to shoot seriously, you will want to handload. $2 a shot for factory match grade .308 gets old fast.
I have shot .308 for years. Last two seasons I went to .260. Past 500m, the difference is dramatic.
Tiriaq, thank you. Are you saying that the .260 performs better than the .308 past 500m? and YES 2$ a round is a bankruptcy promoter. Sooner or later, I will have to learn hand loading.
Not sure what part of Canada you are in but here in Alberta you need .240 minimum caliber to hunt deer with so that would exclude the .223
I think the .308 would be perfect as ammo is reasonably priced with lots of options but the .243 would work as well
KC34, thank you. The .243 is no longer in my sights as it's a huge barrel burner. 308 is looking like a favorite at the moment from all these suggestions.
+1 for 308 for both aspects of target and hunting. and 308 is a breeze to reload for compared to some calibres, lots of data and components out there
BRTS, thank you. 308 seems to be gathering much praise.
308win or 260rem.
SND, thank you. Another 308 point!
