Superglue would defintely work, but IMO it doesn't make the grain 'pop' as much as other finishes, especially with lighter woods.
TruOil would do a great job on the figure of the cedar (did wonders for some bird's eye maple for me recently).
A more durable finish that'll do the same is thinned down epoxy. I use marine epoxy cut with acetone, but regular 2-ton will work - you just need more acetone.
I also like to use the marine epoxy straight. Just rub it on and then wipe off the excess. Gives a more satin finish than the thinned down stuff, but doesn't penetrate and highlight the grain as much.
This is the thinned down epoxy on alligator juniper (works similar to red cedar)
And here is the superglue on the same juniper:
See the difference? It's hard with the smaller pics, but the superglue didn't do a thing to highlight the subtle differences in the grain and slight shading variations in the wood. I was pretty disappointed with it actually.
On really dense woods like cocobolo the superglue does a nice job of sealing the wood and bringing out the figure, but it doesn't need to penetrate deeply do it. With softer woods like the juniper and cedar, as well as really cool figure like quilted/bird's eye maple or quilted walnut you really need something that will penetrate to bring out the best in the wood. TruOil or thinned down epoxy work well, as does Danish Oil... pretty much all the oils really.
