Welcome to the forum!
Storing a growing collection is always a headache and largely done to personal preference. I have a very similar target collection to yours and have kept mine in a growing number of the WH Smith's "Magpie" albums, which are reasonably cheap and secure. The double action ensures coins do not slip out, and the plastic is coin safe. They are not good for display and the folders gradually fail under the weight of coins.
The range of Lindner coin trays are another alternative. They are good for display and very adaptable, but each tray is expensive.
Many new collectors start with coin flips and long boxes, which is simple and practical, but viewing your coins becomes tedious.
Traditionally the serious collector would use the custom made coin cabinets. Others may be able to point you to current suppliers, or you can keep an eye on the auctions. These are much better for display and the cabinets look appealing, but the coins are more open to the environment, and they can become inflexible as your collection expands.
Of course if you are following the American trend towards graded and encapsulated coins, you need an entirely different approach and I have no idea how they tackle that.
