W5500 Crystal selection

Question

Hi, I have read numerous forums and conversations about the correct crystal selection for W5500 and I see lots of people had stability issues which makes me worried. Obviously the datasheet has mentioned some specific characteristics for the crystal: 25MHz, 30ppm Frequency tolerance, 18pF load capacitance. I have four questions: 1- What’s the ESR value I should aim for this crystal? 2- Is HC-49/US package preferred or 4-SMD? 3- Does this look like a good option: (FY2500016) Mouser Electronics FY2500016 Diodes Incorporated | Mouser FY2500016 Diodes Incorporated Crystals 25.000MHz 18pF 30ppm -20 to +70 datasheet, inventory, & pricing. If not what part number have you actually used in production and it worked perfectly? 4- For the load capacitance, is it a good practice to follow design reference from Wiznet which suggests 18pF capacitors. I understand following formula and assuming 5pF Cstray on the paper gives us 26pF not Wiznet’s suggestion of18pF. Thank you,
