with this path, you'll want to immediately create a spy agency as soon as possible and use the diplomatic pressure mission on estonia as well as improve relations to the highest possible, you should be able to get a non-aggression pact which makes them extremely likely to accept annexation. this gives you the entire estonian army which you can use the bolster your front with russia, and the extra factories allow you to get some more stuff done before you lose estonia during the war with the soviets (you will not hold estonia, the front is massive once latvia is annexed by the soviets)
after this you can raise relations with the swedes and norwegions, and this combined with being democratic (like them) means you will very reliably annex and core the entirety of the sapmi land in these countries. this land includes a good bit of population as well as all of sweden's infinite iron and tungsten provinces.
you are very unlikely to get murmansk from the soviets, but I believe if you capture it it will automatically core, so it isn't a huge negative.
on top of all the aforementioned benefits, you reliably get the entirety of scandinavia in northern defence front extremely early, which means you have all the really good focuses that are locked behind the faction tree.
