A real mix of good advice and bad in this thread.
Wood finishing is one of those hard subjects, partly because everyone has their own experience and their own opinion about what worked for them, but mostly because there is so much BS by big companies in the marketing of these products. Wood finishing products are often given all kinds of misleading names - from stains that are actually polyurethanes, to oils that are not oils, to clear-coats with incorrect instructions, to random exotic sounding names given to what are actually common, mundane products.
Linseed oil is a cost-friendly budget oil of limited durability. Boiling it causes polymerization which speeds up cure times. Boiled Linseed Oil is therefore the budget go-to. It will look great at first, but long term it won't hold up. Use it on stuff you plan to sell!
tung oil is much more durable and much better quality, but it's also much more expensive. Get polymerised tung oil (lee valley sells it) so that you don't have to wait a week between coats.
Millions of products have tung oil in the name but have little to no tung oil in the bottle. Tung oil is expensive. If the product is cheap, then it's not really tung oil. If it says "minwax" , then it's not tung oil either.
A stain can make the wood a more pleasing colour, but be warned that stain doesn't actually penetrate very deep, so minor scratches will be very visible as they reveal the wood's true colour underneath the stain. Stains also merely colour the wood by depositing pigment in the grain - they do not actually do anything to seal or protect the wood, so a stain always must be topped by some sort of protective finish - either a film finish like a varnish or polyurethane or an oil finish. Oil finishes are also sometimes blended with wax - like the popular osmo brand finish - and in my opinion that does give increased durability.
If you want to understand wood finishing, there is absolutely only one place to start, the book "understanding wood finishing" by bob flexner. He sorts through all the marketing BS and gives the scientific facts on each question. He debunks all the myths and leaves you with just the truth of the matter. Can't recommend it more.
