• STEP 1: REGISTRATION: Participants must be registered for step 1 after they have signed institutional consent for CAR T-cell leukapheresis but prior to the start of lymphodepleting (LD) chemotherapy for commercial CAR T-cell product
• STEP 1: REGISTRATION: In the opinion of the enrolling physician, participants must be felt to be a candidate for CAR T-cell therapy with plans to be treated with Food and Drug Administration (FDA) approved commercially available CD19 CAR T-cell construct.
• Participants must qualify for commercially approved CD19 CAR T-cell therapy per FDA package insert.
• If the CAR T-cell product does not meet parameters to be given as an FDA approved product (i.e. does not meet specification criteria mandated by FDA and is infused under an expanded access protocol \[EAP\] or single participant investigational new drug \[IND\]) the participant will be taken off of study and no longer be eligible for step 2 randomization
• STEP 1: REGISTRATION: Participants are permitted to receive or have received 'bridging therapy' after CAR T-cell leukapheresis. However, participants must not receive polatuzumab vedotin, and/or mosunetuzumab as part of bridging therapy.
• Bridging therapy is defined as lymphoma directed therapy administered between leukapheresis and the start of LD chemotherapy. This includes cytotoxic chemotherapy (e.g.: bendamustine and rituximab \[BR\], rituximab, gemcitabine and oxaliplatin \[R-gem/ox\]), radiation, corticosteroids, as well as novel therapies such as BTK inhibitors (e.g.: Ibrutinib), immunomodulators (e.g.: lenalidomide), monoclonal antibodies (e.g.: rituximab, obinutuzumab, tafasitamab) antibody drug conjugates (e.g: loncastuximab), checkpoint inhibitors (e.g.: pembrolizumab, nivolumab), clinical trial treatments, etc.
• If a participant receives polatuzumab vedotin or mosunetuzumab as bridging they will ineligible to continue on step 1 registration portion of the study and be ineligible for step 2 randomization
• STEP 1: REGISTRATION: PET-CT scan must be planned for completion within 60 days prior to the start of LD chemotherapy.
• All pre-CAR T-cell therapy disease must be assessed and documented on the baseline/pre-registration tumor assessment form.

If the PET-CT scan after completion of bridging therapy is consistent with complete remission per Lugano criteria as determined by enrolling physician, that participant will be ineligible for step 2 randomization.
• Participants are permitted to receive corticosteroids after leukapheresis without the need to repeat a PET-CT scan. If steroids are used, they must be planned to stop no later than 3 days before CAR -T cell infusion.
• If response assessment by central review cannot be completed (I.e., poor quality of PET-CT scan, PET-CT performed out of window, etc.) this would be recorded as 'inadequate assessment' and patient would not be eligible for randomization
• STEP 1: REGISTRATION: Participants that have previously been treated with polatuzumab vedotin or mosunetuzumab prior to CAR T-cell leukapheresis for either indolent or aggressive NHL are eligible as long as the participant did not have refractory disease or progression/relapse within 6 months of the last infusion with either agent
• STEP 1: REGISTRATION: Participants must be planning to receive CAR T-cell infusion no earlier than 2 days and no later than 14 days after completion of the last day of lymphodepleting chemotherapy.
