If your budget allows it, you should go with the Dell OptiPlex SFF 7020 2024 as it is running a newer generation CPU. This is not to say that HP EliteDesk 800 G1 SFF is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The HP EliteDesk 800 G1 SFF has 4 RAM slots while the Dell OptiPlex SFF 7020 2024 has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.

Additionally, if you will be needing a lot of RAM, better go for the Dell OptiPlex SFF 7020 2024 as it has the ability to run 64 GB of RAM. The HP EliteDesk 800 G1 SFF can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the HP EliteDesk 800 G1 SFF has 10 USB ports. The Dell OptiPlex SFF 7020 2024 is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP EliteDesk 800 G1 SFF comes with 2 ports, while the Dell OptiPlex SFF 7020 2024 has only 1. If you are planning to use multiple monitors, the HP EliteDesk 800 G1 SFF is the better choice.
The Dell OptiPlex SFF 7020 2024 comes with an HDMI port, while the HP EliteDesk 800 G1 SFF does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).
SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the HP EliteDesk 800 G1 SFF is better equipped as it comes with 3 SATA slot(s), while the Dell OptiPlex SFF 7020 2024 has 2 slot(s).
If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the Dell OptiPlex SFF 7020 2024. Sadly, the HP EliteDesk 800 G1 SFF has no such slot, and you will be forced to use the SATA interface instead.
Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!
Power Supply
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Dell OptiPlex SFF 7020 2024 comes with a decent 300 Watt PSU, but the HP EliteDesk 800 G1 SFF has a more powerful one rated at 320 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
