First and foremost, you should spend your time acclimating yourself to combat with your ship by becoming more proficient with dog fighting. Nav Beacons are in open space so you have less to worry about than an RES as far as running into objects surrounding the environment like meteors. The best Nav Beacons in my experience are the ones located in systems that have high populations, a pirate type faction, and with multiple RES sites. They generally spawn the most pirates and they spawn more frequently. Most importantly, there is always a police force presence and they are well placed within the environment, compared to a RES site where the police may not be anywhere within range of the pirates to assist your attack.
Second, you absolutely need a KWS to capitalize on your bounties, and if you have not joined a PP, consider joining a PP that affords bounty bonuses and receives bounty bonuses based on ranking, like Arissa for instance. This way you could double your bounties during farming.
Third, stick with smaller ships, which include for the most part, but do not limit the following, Sidewinders, Eagles, Vipers, Cobras, DB Scouts, and Imperial Couriers. However, just take into consideration that Couriers despite their weak hulls, have very strong shields commensurate with Vultures and even Pythons. Larger ships you should attack only when police are already engaging them, and make sure that you are not attacking a set of wings that are not already defending themselves against police attacks.
Finally, when you are comfortable with your ability to fly, try a Low Intensity RES or RES, which may have a plethora of ships, big and small, and test your skill against larger ships. Even though the ships may be much larger than the ones you practiced with the NPC commanders in these environments are generally low rated at combat, which means you can dispatch them fairly easily and many of them will not have shields making your job easier.
